Uma Thurman recently caused a stir with her dramatically different appearance. And while plastic surgery rumors swirled, the Pulp Fiction star said it was all due to a makeup change. But she’s not the only celebrity who has been unrecognizable. Check out OK!’s list of 22 stars who had us scratching our heads by drastically changing their look.

Uma Thurman: Plastic surgery rumors swirled when Uma Thurman stepped out to promote her NBC miniseries The Slap. While many assumed she’d had a nip and tuck, Thurman insisted it was simply a new style of makeup. She said on the Today show, “I know I look weird! I don't know, I guess nobody liked my makeup.” Her makeup artist Troy Surratt confirmed to Refinery29.com, “We did a much stronger brow with a red lip.”

Cher:  The star has admitted only to getting breast implants, a nose job, and work done on her mouth.  She said that the first surgery she got was a rhinoplasty, after she saw herself in a movie screen for the first time: “I looked at myself up there on that screen and thought, I'm all nose.” Lately Cher has looked suspiciously wrinkle-free while being close-mouthed about what she’s had done, saying, “If I want to put my breasts on my back, it’s nobody’s business but my own.”

Kylie Jenner: The Keeping Up with the Kardashians sister was the subject of pointed plastic surgery accusations over her suddenly enormous lips! But Kylie has denied she got lip enhancement and attributed her look to makeup. And she complained to E! about comments that her pout looks unnatural, “I feel like everyone has been talking about it for months, so I'm kind of sick of it.”

Lara Flynn Boyle: She looked radiant on the cult TV show Twin Peaks, but now, Boyle is puffy and almost unrecognizable. The reclusive actress has never addressed plastic surgery rumors.

Kathy Griffin: In her memoir, Kathy Griffin: My Life On The D-List, the Fashion Police co-host disclosed multiple plastic surgeries, including a nose job, brow lift, Botox injections, chemical peels and liposuction. In 2008, however, Kathy claimed her addiction to plastic surgery was done! “I've been off the junk, as I call it, for five years. It didn't help me one bit," she sighed.

Melanie Griffith: The Working Girl actress admitted to getting a breast-lift in 1991 after the birth of her second child-- and also having collagen injections to her lips. Britain's Mirror quoted Melanie in 1999 as saying, “I have been thinking about plastic surgery, but I'm not saying where. Turning 40 is difficult. I often think, 'If only someone could put a zip down the back of me and tighten everything up!’”

Kris Jenner: The reality TV matriarch and talk show hostess is always changing her look and she admits surgeons gave her help. In 2011, Kris was seen getting a face lift on Keeping Up with the Kardashians to look pretty for daughter Kim’s wedding. And she also underwent breast implant surgery on the show—her second boob job. Kris admitted she got her first set of implants years before, so she needed a new pair!

Kim Kardashian: Plastic surgeons who have not treated the reality star have speculated to RadarOnline.com that she’s had work done on her face, a charge the reality TV queen star vehemently denies. Still, she’s admitted to Botox and Dr. Anthony Youn (who has never treated her) told Radar he believed Kardashian had a nose job and lip plumping done.

Lisa Rinna: The Real Housewives of Beverly Hills and former soap opera star has spent a lot of time laughing about her famous fat lips. She admitted to having had silicone lip implants years ago.  Recently, she went under the knife to remove them and make her lips look more natural. But they’re still huge!

Farrah Abraham: The Teen Mom turned porn star was left with a swollen upper lip after a botched implant!  Although she soon got the problem fixed, it’s not the first time Abraham has changed her look as she’s admitted to breast augmentation surgery, upgrading her cup size from a C to a D, and has also had a nose job and chin implant. Abraham has explained, “I want to look my best.”

Rose McGowan: McGowan said she had some corrective surgery to heal a cut under her eye after a 2007 car accident. But is that all? The Charmed star’s face looks incredibly different from when she started out in Hollywood.

NeNe Leakes:  The Real Housewives of Atlanta queen bee is a much different woman from her struggling younger days—she’s admitted to a breast lift, rhinoplasty, and liposuction. And she wouldn’t hesitate to have more! “If anything falls, I pick it up!” Leakes told US Weekly.

Heidi Montag: The Hills reality star followed up her 2007 nose job and breast augmentation with a ten-hour series of procedures in 2010 that included a mini brow lift, nose-job revision, chin reduction, neck liposuction, and buttock augmentation, among other things! Heidi told People magazine, “I am absolutely beyond obsessed,” about having plastic surgery done. She added, “I just wanted to feel more confident."   

Sharon Osbourne: The Talk hostess revealed on the show that she had vowed to have “no more” plastic surgery. “I have been looking at pictures of myself recently….And in a lot of shots, my face looks plastic and at certain angles,” Osbourne candidly admitted.  “I was like, 'Oh, dear. Oh, I should never have done that. Oh, that's a bad one.' So I'm like, 'No more. No more abuse.’” People magazine reported in 2003 that Osbourne had gotten a facelift, tummy tuck, liposuction, leg lift, breast lift, and her lips enlarged with collagen.

Taylor Armstrong: The onetime Real Housewives of Beverly Hills star, whose frozen face and duck lips caused chatter, admitted to US Weekly to having “little injections here and there,” without specifying what—and where! Armstrong admitted, “It makes me feel good, so I do it.”

Renee Zellweger: Where have you gone, Bridget Jones? Zellweger, 45, appeared unrecognizable at the 2014 Elle Women in Hollywood Awards. But the Oscar winner fought back against plastic surgery speculation by simply telling People magazine, “I'm glad folks think I look different! I'm living a different, happy, more fulfilling life, and I'm thrilled that perhaps it shows.”

Daryl Hannah: The Splash sex symbol who once dated JFK Jr. looks much different from when she was younger. People wonder if she’s had work done to her brow, lips, and cheeks.

Janice Dickinson: The frequent reality show star looks vastly different from her supermodel days and she hasn’t been shy about admitting to massive amounts of plastic surgery, saying, “There’s no such thing as too much.” Janice has had a breast enlargement, tummy tuck, neck and facelifts, liposuction and Botox. In 2007, Janice revealed, “I’m addicted to cosmetic surgery.”

Tatum O’Neal: In 2013, the Oscar winner stepped out not looking quite herself with puffy lips and an immobile face. Dr. Anthony Youn, who has never personally treated O’Neal, told OK! he suspected her shockingly different appearance could be due to “injections, Botox, and chemical peels.” 

Kenny Rogers: “The Gambler” singer startled fans with his new face in 2006 and admitted in an interview with People magazine he’d had extensive plastic surgery. “I had so many lines coming in at the side of my eyes….so I went in and got my eyes done, and I’m not happy about it…they’re too tight around the eyelids for me. It drives me crazy,” Rogers said.

Bruce Jenner: In 2009, the Olympic hero told Access Hollywood he’d had a nose job and partial face-lift way back in 1984. “‘Because you’re Bruce Jenner, Olympic champ people said, ‘Oh my gosh, you shouldn’t be doing things like that,’” said the Keeping Up with the Kardashians star who is reportedly now undergoing a sex change. Jenner had a second face lift later at around age 60 to correct the previous procedures. “I had it done and not even my close friends knew I had it done,” he revealed.
