Unrecognizable Celebrities Who Have Sparked Plastic Surgery Buzz.. as Jessica Simpson, Megan Fox and More Famous Faces Hit Back Against Rumors

Hollywood is known for going under the knife... and these famous faces have been rumored to have done just that to change their appearance.

RadarOnline.com can reveal unrecognizable celebrities who have sparked plastic surgery buzz.

From buccal fat removal to fillers, Amelia Gray Hamlin is no longer a stranger to plastic surgery buzz.

While the model has never admitted to undergoing plastic surgery or cosmetic enhancement, she previously confirmed she had a breast reduction due to a strep infection and mastitis in her left breast. She reportedly developed an infection after her nipple piercing snagged on something.

"When I tell you like my breasts were this big – I didn't just get those down, like, naturally," Hamlin shared, adding, "I'm not going to lie, I've never talked about this, but I had to fully get surgery. I had to get a breast reduction."

Her mom, Lisa Rinna, also defended her amid the speculation, saying Hamlin has "the most gorgeous lips."

Like other celebrities, Hunter Tylo has sparked plastic surgery rumors due to her changing appearance.

The Bold and the Beautiful alum never acknowledged any cosmetic procedures, though a celebrity plastic surgeon commented on the suspected plastic surgery in a 2012 interview.

"Hunter Tylo appears to have had some Bold plastic surgery, but has it made her less beautiful? Her lips look like they've been inflated to massive proportions, possibly from excessive injections of fat," Dr. Anthony Youn told RadarOnline.com. "Her cheeks also appear overly plumped, possibly from fat injections as well. Her face is excessively smooth, too smooth to be natural, in my opinion."

He added: "I suspect that she's undergone hefty doses of Botox to look this way. Botox may also explain the change in her eyebrows."

In the same interview, Dr. Youn gave Tylo advice, believing she had gone too far.

"If I could give her one piece of advice, it'd be to leave her face alone for a while. She's such a natural beauty. She doesn't need any plastic surgery," he continued.

Jessica Simpson sparked plastic surgery rumors again after her appearance at the 2025 MTV Video Music Awards.

After fans said they could no longer recognize her, plastic surgeons weighed in on the I Wanna Love You Forever singer's transformation.

"While we can't say for certain since we did not perform any procedures on her, her appearance suggests a tightened, refreshed look," Dr. David Pincus of New York's Pincus Plastic Surgery, who said Simpson looked "phenomenal" at the event, explained to Daily Mail.

He added: "Her lips appear freshly filled within the last week or two, giving a very full look that many women love."

The plastic surgeon noted Simpson has been open about trying lip filler, non-surgical facelifts, and tummy tucks in the past.

Then, for her appearance at the MTV VMAs, she may have had Botox in the forehead or brow area, Dr. Pincus suggested.

For years, Madonna has dealt with speculation that her transformation comes with surgical help.

According to Dr. Barry Weintraub, the Queen of Pop had at least "twelve cosmetic facial procedures" to help maintain her youthful glow. These included dermal filler injections and a brow lift.

"Her cheekbones are much, much fuller, and that is secondary to either fat or filler injections. We see this all too often in our field, but unfortunately, people tend to fill their faces to try to plump out wrinkles," he added. "She also has... two little dimples on each side [in the original picture], which you don't see now because they are filled with fat."

Despite her unrecognizable transformation, Megan Fox swore she had never had any cosmetic work done to her face – though she confirmed her breasts "have been fake" since she was in her 20s.

"I got them done in between the first and second Transformers. But I had them done 'conservatively,'" Fox revealed in an episode of the Call Her Daddy podcast.

She then denied having threads or a facelift "of any kind."

"That's not because of some moral thing, I just… don't really believe they work, and I'm also afraid that they would interfere when I do need to have a facelift," Fox continued.

In a TikTok video, Mike 'The Situation' Sorrentino shut down plastic surgery rumors after social media users commented about his "different" appearance.

"I definitely got a ton of responses thinking I had gotten a facelift or new eyeballs and cheeks from Zimbabwe," he said. "I definitely didn't do that."

Instead, the Jersey Shore star achieved his new look by going to the gym and tanning.

Sorrentino added: "I haven't cheated on my diet, and I definitely haven't shown anybody the results yet. I plan to do that shortly."

In 2008, TMZ released a report about Priscilla Presley's botched cosmetic procedure performed in 2003 by an unlicensed doctor, Daniel Serrano.

In the years thereafter, Presley sparked speculation of facelifts, nose jobs, and Botox, though she has not made direct admissions to the rumors.

After years of speculation, Simon Cowell confirmed he had Botox and fillers to alter his appearance – and he regretted undergoing the cosmetic enhancements.

"There was a stage where I might have gone a bit too far. I saw a picture of me from 'before' the other day, and didn't recognize it as me first of all," he told The Sun in 2022.

During a December 2024 appearance on Today, Victoria Beckham dismissed speculation that she had undergone surgery, specifically a nose job.

"I like to draw," she said, referring to contouring her nose. "I have to say, there's been a lot of people in the past that have said to me that I've had some kind of surgery on my nose. I have never, ever, ever, ever ... No, never.."

However, London-based cosmetic expert Dr. Jonny Betteridge disagreed. He shared a photo of the former Spice Girls member and suggested she had undergone a facelift to maintain her appearance after "overfilling."

"Often a deep plane face and neck lift is then considered the best option, which I think she's had done," he assumed.

After dealing with plastic surgery rumors for years, Zac Efron earned praise when he debuted a "normal" look at the premiere of his Netflix film, A Family Affair, in 2024. At the time, fans suggested the High School Musical alum appeared to have his fillers dissolved.

Efron first sparked a buzz when he participated in Earth Day! The Musical in 2021. He then addressed the backlash he had received in a 2022 interview with Men's Health, saying a freak accident at his home left his chin severely injured.

"He'd been running through his house in socks and slipped, smacking his chin against the granite corner of a fountain," reporter Lauren Larson detailed. "He lost consciousness, and when he woke up, he recalls, his chin bone was hanging off his face."

As Efron worked with a specialist to regain his facial muscles' strength, his masseters "just grew" and "just got really, really big."
