20 Celebrity Transformations That Left Us Speechless In 2025

2025 has brought new hits, beloved films and shows, and also plenty of celebrity transformations that left fans doing a double take on their favorite stars.

Some A-listers impressed with their toned physiques, while others sparked plastic surgery speculation or challenged beauty norms by aging gracefully in front of the world.

In other cases, iconic actors made rare public appearances that left jaws dropping at how much they had changed.

Without further ado, here’s a list of 20 stars who made headlines for their physical transformations this year.

#1 Maggie Wheeler

Maggie decided to challenge societal beauty standards for women and proudly embraced her gray hair this year.

The 63-year-old actress, best known for her role as the iconic Janice Hosenstein on Friends, attended an anniversary event for Everybody Loves Raymond, in which she played Linda Gruenfelder.

Maggie glowed in a shimmering golden suit, with the jacket styled over a white blouse.

“She looks radiant! I love that,” one fan said, while a second user added, “Maggie was stunning then and still is now.”

#2 Susan Boyle

Many netizens agreed that Susan, who rose to fame on Britain’s Got Talent in 2009, looked “unrecognizable” when she appeared at the Pride of Britain Awards in October.

The Scottish singer, now 64 years old, debuted a blonde bob, ditching the natural curly locks she rocked on the talent show.

“Looking as beautiful as ever, Susan. Whenever I see your photo, my brain sings I Dreamed A Dream,” one fan said, referencing the song Susan auditioned with—the one that drastically changed her life.

Since appearing on Britain’s Got Talent, Susan has sold more than 25 million records and received two Grammy nominations. Her debut album was the best-selling album internationally in 2009.

#3 Lindsay Lohan

In 2025, Lindsay reprised her role as Anna Coleman in Freakier Friday, the Freaky Friday sequel that premiered twelve years after the original Disney film.

In the movie, the 39-year-old appeared blonde, and her signature freckles were nowhere to be seen.

“I want whatever she’s been doing to her face. She looks AMAZING,” one fan said.

“I need a Lindsay Lohan makeover,” shared another netizen.

Despite plastic surgery speculation, Lindsay has consistently denied going under the knife. She has revealed, however, that she has received Botox injections and laser treatments

#4 Oliver Platt

Oliver was pictured looking significantly slimmer in a rare public appearance while walking in Manhattan last June.

The 65-year-old actor is known for starring in Flatliners alongside Julia Roberts and for portraying psychiatrist Dr. Daniel Charles in Chicago Med. You may also recognize him for Hulu’s The Bear, in which he plays Jimmy “Cicero” Kalinowski.

The father of three sported a casual outfit that included a gray collared shirt, jean shorts, and tennis shoes.

He also attended a dinner for the cast and producers of The Bear that month.

Dominic Purcell

Dominic famously played Lincoln Burrows in the TV series Prison Break, which ran between 2005 and 2017. At the time, the actor sported a clean-shaven look with his hair also shaved.

However, the 55-year-old Aussie considered it was time for a change and debuted a long, white bearded look this year.

“For a second, I didn’t recognize you,” one fan said of Dominic’s new look.

“Rocking that beard, mate!” complimented another.

Mandy Moore

The actress and singer turned heads at the 2025 Inspiration Awards in October, with many fans speculating about possible cosmetic procedures that may have altered her natural features.

Mandy is known for portraying Rebecca Pearson in This Is Us and for starring in Nicholas Sparks’ romance A Walk to Remember.

“I can’t figure it out how this can be the same person. Mandy Moore was such a natural beauty, why get work done to the point of being unrecognized?” one confused fan asked.

“What the hell happened to Mandy Moore? Is it even the same person?” echoed another.

Meghan Trainor

Meghan became world famous for her 2014 hit All About That Bass, in which she celebrated her curves and said she refused to be a “stick figure silicone Barbie doll.”

This year, the songstress lost a significant amount of weight through physical exercise, dietary changes, and weight-loss jab Mounjaro.

“I’ve worked with a dietician, made huge lifestyle changes, started exercising with a trainer, and yes, I used science and support (shoutout to Mounjaro!) to help me after my 2nd pregnancy,” the 31-year-old star shared in April.

Meghan began her transformation in 2022, telling Entertainment Tonight that she had lost 60 pounds (approx. 27 kg) through diet and exercise.

She also underwent breast augmentation surgery this year, confirming the operation last May by singing on stage, “It’s pretty clear, I got some new b**bs,” instead of “It’s pretty clear, I ain’t no size two.”

David Dobrik

David stunned viewers when he unveiled his “insane” body transformation after a two-year hiatus on YouTube.

The content creator, who boasts 17 million subscribers, returned to the platform in January with a 14-minute video documenting his physical transformation.

“This is crazy that I look like this. I don’t know what happened,” said David, who focused on reducing his body fat with personal trainer Ilya Fedorovich.

By the end of his health journey, David’s body fat percentage had dropped to 13.1% and he had gained 10.5 pounds of muscle

Kim Novak

The 92-year-old actress made her first major public appearance in a decade to accept the Golden Lion for Lifetime Achievement award at the 82nd Venice International Film Festival.

Kim is best known for starring in Alfred Hitchcock’s Vertigo, considered one of the greatest films of all time. She retired from acting in 1991 after a “painful” experience filming Liebestraum.

“She’s one of the best actresses to ever grace the screen,” one viewer said after seeing Kim at the prestigious film festival this year.

“Why so much cosmetic surgery? She’d be better without it,” added another.

Kim reacted to the public scrutiny surrounding her appearance, writing in 2014, “After my appearance on the Oscars this year, I read all the jabs. I know what Donald Trump and others said, and I’m not going to deny that I had fat injections in my face."

The US President had posted on social media that Kim "should sue" her plastic surgeon.
