Celebrities are known for being chameleons. After all, they have to convince us, the general public, that they are different people in every film or TV show they do! Makeup, hair, wardrobe, and voice coaching can help actors to develop characters and truly transform into their roles… but some celebrities take transformative measures off-screen, too. The true transformation comes when some celebrities become unrecognizable on their own accord.

Transformation is not one-size-fits-all. Some celebrities go through dramatic weight loss while others turn to cosmetic surgery and enhancement to change their looks. In fact, celebrities are becoming increasingly unrecognizable thanks to the technological advances in cosmetic surgery. In decades past, changing your face and body so extremely just wouldn’t have been possible, but now, it seems people can truly take their appearance in almost any direction they choose.

We’d bet you’re thinking about female celebrities when you think of cosmetic surgery and transformations. However, male celebrities are no stranger to reinvention, either. Some of the celebrity transformations on this list may absolutely shock you.

From accomplished actors to reality stars, these celebrities have reinvented themselves and changed their lives… for better or worse. Some transformations are clear upgrades, while some still leave us scratching our heads. Let’s just say, in many cases, “anti-aging” procedures do anything but turn back the hands of time. From the “Why?” cases to the “OMG!” makeovers, we’ll cover the top fifteen celebrity transformations to date.

15. Jonah Hill

Jonah Hill rose to fame following the commercial success of hit teen comedy “Superbad.” He starred as an overweight high schooler, eager to lose his virginity to then-unknown Emma Stone. Since then, Hill has created a career tapestry of interesting films, ranging from “Wolf of Wall Street” to “War Dogs.” Hill is known for being great at both dramatic and comedic acting. While his body of work is diverse, his body itself has always looked relatively… the same. However, this spring, Hill debuted a newly slim body and a new haircut. Since then, he’s been praised for his new buff appearance by fans and critics alike.

14. Steve Carell

From dweeb to babe! Steve Carell is one of the greatest character actors of our time. We, of course, know him as the unforgettable Michael Scott on “The Office,” but his roles in the “Anchorman” and “Despicable Me” franchises are equally hilarious. Carell has also made a name for himself as a serious dramatic actor, such as in films like “Foxcatcher” and “The Big Short.” From his comedic roles to his dramatic ones, Carell is basically always playing an out-of-touch, nerdy, middle-aged guy not unlike his title character in “The 40-Year-Old Virgin.” Well, Carell has finally shed that dorky image by debuting a new silver fox haircut and updated style. When asked how he felt to be called “a total babe” now, he said he is “busting with pride.” We bet Ryan Gosling is, too.

13. Kylie Jenner

The Kylie Jenner transformation is one of the most talked about of our generation. In fact, Kylie has become a pseudo-spokesmodel for a certain kind of transformation: Cosmetic surgery for teens. While the exact cosmetic surgeries Kylie has undergone remains hotly debated, no one can deny that she has completely changed her looks in a matter of a few short years. Sure, we all change during adolescence, but getting a new face and body typically isn’t in the cards for everyone. However, coming from a family business that knows how to capitalize on anything… even teen surgery scandals… Kylie has taken the infamy and made bank. Her lip kits, launched after she debuted a much-enhanced pout herself, continue to sell out worldwide.

12. Caitlyn Jenner

You didn’t think we’d only include one member of the Kardashian-Jenner clan did you? When you talk about celebrity transformations, few are as memorable as Caitlyn Jenner. Caitlyn, then Bruce, rose to fame in the 1980s, following tremendous success as an Olympic athlete. Her career was then as a motivational speaker and spokesperson, eventually marrying the ex-wife of Robert Kardashian, Kris. Under Kris’s management, Jenner went on to star in “Keeping Up With the Kardashians.” As the tight-pocketed, strict dad to Kris’s zany antics and lavish spending, Jenner then grew an even bigger fanbase. While many speculated that Caitlyn’s long hair and changing body could be signs of transitioning or experimenting with gender, it wasn’t until Caitlyn famously opened up in 2015 about expressing the female gender and changing her name.

11. Khloe Kardashian

While Caitlyn and Kylie’s transformation definitely receive more public scrutiny, one cannot underestimate the transformation of older sister Khloé. Khloé Kardashian was the third child of Kris Jenner and Robert Kardashian. It has long been rumored that Khloé had a different father from siblings Kim, Kourtney, and Rob because she had a different skin tone, body type, eye color, and hair color than all of her siblings. Khloé has been open in the past about struggling with her weight and feeling like the fat, ugly sister amongst the clan. After her public divorce with Lamar, Kardashian published a book and started a TV show, all inspired by her “revenge body” and health journey. Now, years later, Khloé looks better than ever and is certainly not the “fat” or “ugly” one anymore!

10. Snooki

When “Jersey Shore” premiered on MTV almost a decade ago, no one could’ve predicted the publicity storm it would’ve created. Reality shows just like it, many even on MTV, had come and gone and sometimes flopped. What was it that made this show about house-sharing-strangers so popular? One word: Snooki. Snooki became the breakout start of the show, based on her rants about Fossil watches and all around drunken antics. She seemed to always be halfway between a blackout and a hangover and it was hard to look away. She was a tiny, though plump fixture in the media. Since then, Snooki has rehabbed her image. Thanks to major weight loss, cosmetic surgery, and a new family life, Snooki is no longer the “hot mess” we once knew.

9. Chris Pratt

Is there anything more fulfilling than the chubby, goofy guy you already love getting majorly hot? We think not. Chris Pratt was a fan favorite on the NBC series “Parks and Rec” as Andy Dwyer. Andy was an eager-to-please, well-meaning idiot with a penchant for lyrical rock music. He loved to eat and be lazy and Pratt definitely let the role dictate his physical appearance… if you know what we mean. Since “Parks and Rec,” Pratt has launched a film career and turned into a major hottie. “Guardians of the Galaxy” cemented him as a total babe, with women ogling his new muscles, abs, and chiseled jawline. In fact, his new physical beauty is our only explanation for “Jurassic World” being made in the first place.

8. Ariel Winter

Ariel Winter is a recent tabloid and online fixture. Having literally grown up on camera, Winter is now an adult and is making sure people treat her as one. From racy photos to PDA-filled lunches, Ariel is living life as a grown woman and not apologizing. For fans of “Modern Family” this transformation can be a lot to handle. Winter stars as a Alex, the daughter of Phil and Claire Dunphy on the popular ABC series. On the show, Winter’s character is precocious, extremely intelligent, and witty. She is wary of females who dress sexually and is a hardcore feminist. While Winter may be all of those things in real life, her new public persona is nowhere near that of her famous character. After she underwent breast reduction surgery, Winter has seemingly taken every public appearance as a chance to show off her body of work, shall we say.

7. Zac Efron

If Ariel Winter is the story of an awkward teenager turned sex symbol, then Zac Efron is the male lead of that same story. Efron has worked in Hollywood from an incredibly young age, thanks to his talent, sparkling blue yes, and great smile. His big break came in the movie “High School Musical” as a basketball star/singer. Since then, he’s continued to work steadily in the business, barring a short stint in rehab. While it’s not surprising he continues to find work as an actor, it is shocking how unbelievably shredded he is now. It seems like just yesterday he was a scrawny, gap-toothed man with a mushroom cut. Now, he is one of the fittest, most muscular men in Hollywood. Just ask one of the ten people who saw “Baywatch” this year!

6. John Goodman

Does anyone else hear the “Roseanne” theme when they look at John Goodman? He belly-laughed his way into American hearts as Rosanne’s husband on the series and has been a Hollywood mainstay ever since. Known for his humor, gregarious voice, and large size, John Goodman was like the Santa Claus of comedic actors. However, he has banished that image recently by debuting a newly svelte figure. Always known for being tall, Goodman recently lost tens of pounds, leaving his tall frame as straight as a board. We’re glad he’s taken measures to be healthier, so he can hopefully be around longer, but we can’t help but miss the old Goodman.

5. Katy Perry

Katy Perry has always been known for her costumey style and amazing body. From her “I Kissed a Girl” days to “Firework,” Perry has been the curvy, dark-haired counterpoint to Taylor Swift’s waify blonde persona. In 2017, Perry announced she was changing her artistic expression and image to reflect her political views and life as a feminist. What fans didn’t realize, though, is that meant changing how she looks completely. The black-haired, pin-up throwback is no longer here. Instead, we have a shaved-head blonde Perry with no red lipstick in sight. While both “versions” of Perry are sexy, many of her fans have criticized her leaving her old image behind as ungrateful.

4. Dwayne “The Rock” Johnson

Are you rolling your eyes at us calling Dwayne Johnson a transformation? If yes, that’s because you haven’t seen that turtleneck, fannypack photo of him before his rise to fame. While there’s no denying that Dwayne Johnson was always a tall guy, he seems to be aging in reverse otherwise. Sure, he’s bald now, but his receding hairline at the age of twenty aged him far more than his beautiful shiny head does now. Furthermore, he has completely lost his gut and gained about one hundred pounds of pure lean muscle. An even more impressive transformation? Johnson is one of the only professional wrestlers to successfully transition his career into long-term Hollywood success… and possible presidency?

3. Lil Kim

Lil Kim is known as a pioneer for female rappers. In the nineties, she was known for her contributions to the art, as well as her personal relationships with larger-than-life celebrities like Notorious B.I.G. and Diddy. One of her most famous public appearances involved a very tight bodysuit and just one pasty that no one will ever forget. While she is known for her risk-taking talent, her fans were shocked to see her on “Dancing with the Stars” with what we can only assume was some bad cosmetic surgery results. Lil Kim is now unrecognizable thanks to what looks like a facelift and cheek implants which did nothing to accentuate her underlying natural beauty.

2. Haley Joel Osment

Who could forget Halle Joel Osment as a child actor? He had those brilliant almond-eyes, the cutest voice, and, oh yeah, he saw dead people. From “The Sixth Sense” to “Pay it Forward,” Osment is one of the most beloved child actors of our time. While many child actors fall victim to addiction, Osment has largely avoided controversy while successfully transitioning into a successful adult actor. Recently, fans were shocked to see him on cult TV show classic “Silicon Valley” where he looked like a different human being. The once tiny, adorable Osment is now an overweight, burly guy with a huge beard.

1. Lara Flynn Boyle

With the recent resurgence of “Twin Peaks” on Showtime, fans have been wondering why Lara Flynn Boyle isn’t involved with David Lynch’s reboot. While nothing has been confirmed publicly, it has been speculated that Boyle wanted to join the reboot, but the creator turned her down due to her difficult nature and dramatically changed looks. After all, the reboot was supposed to give fans a sense of familiarity with the characters, and the extent to which Boyle’s looks have changed would need some serious backstory. A natural beauty, Boyle rose to fame in the nineties, reaching peak notoriety as the much younger girlfriend of Jack Nicholson around 2000. Now, Boyle has not been in mainstream films or television for years. Her face is unfortunately bloated, swollen, and misshapen from cosmetic surgery beyond recognition. This is a true cautionary tale that sometimes (usually) natural aging is the better choice.
