Celeb Transformations In 2025 We'll Never Forget

A new year means a new look for many celebs, and in 2025, several of the most famous faces have taken this mantra by the horns, changing things up in a big way. While some of these transformations hint at whispers of plastic surgery, others are simply the result of a new style, hair, and shifts in a makeup routine. For others, there's been an increased focus on fitness and movement. From Mandy Moore to Keke Palmer, it seems everyone on Hollywood's A-list has been making big changes.

For example, Lizzo has been in the spotlight due to her weight loss transformation; but that's not the only way she's changed. The singer has also completely revamped her style. While the singer is still just as daring, she's shifted into a more glamorous vibe. Meanwhile, Anne Hathaway has changed so much that her transformation kickstarted plastic surgery rumors. For others, like Keke Palmer, a new haircut changed everything. It's not uncommon. After all, there's a whole host of celebrities who took a stunning leap from long hair to short, and the shocking new hairdo had a ripple effect on the rest of their style. Whatever the particular changes have been, all of these celebrities have completely revamped their style in 2025 and they look fabulous. 

Mandy Moore completely shocked people when she stepped out at the Step Up's 2025 Inspiration Awards in Los Angeles in September 2025. There were so many things that had transformed about the star. For one, her hair was much longer than she's worn in years past. She also wore it sleekly parted down the middle in a minimalist style. But Moore's clothing was also a departure for her, signaling a new era of elegant robing. She wore a leather mini skirt with black tights and a draped blouse in ivory. The red lipstick added to this new look for Moore. 

Olandria Carthen completely blew up on Love Island USA season 7. Since then, the star has been strutting her stuff with A-listers, like taking in New York City fashion week. She even walked in the Sergio Hudson show in September 2025. It was out and about at these events that people noticed Carthen's transformation. Prior to, Carthen sported a more playful look. She had copper hair and dressed in a younger, more playful style. However, by the fall of 2025, Carthen was on a whole new level. Her sleek locks and killer street style showed that she was elevating her look. 

Anne Hathaway broke the internet when she attended the Ralph Lauren's Fall 2025 show in New York City in April 2025. The star looked radiant and quite different. Prior to, Hathaway was fond of wearing her hair in bangs and decking herself out in sparkly looks that gave off a youthful sparkle. However, 2025 was a whole new vibe for her. Sleek was the name of the game. Hathaway wore her hair pulled back in a tight ponytail. Her look was muted and subdued and yes, there were whispers of plastic surgery. Whether or not that's true, her upgraded, minimalist style is a bold, new chapter for Hathaway. 

There's a psychology behind dying your hair that inspired the phrase: Change your hair, change your life. Nothing could be truer for Keke Palmer. In August 2025, the triple-threat performer debuted a copper pixie cut, a totally new look for the star who has traditionally favored longer hair. The cut inspired a whole new wardrobe, as Palmer experimented with edgier outfits. In photos shared to Instagram, she can be seen wearing brighter colors and more youthful garb. It looks like a playful era for the actor and singer. 

Known for her role on "The Bachelorette," Kaitlyn Bristowe became a mainstay of "The Bachelor" franchise, and as a result, her face become associated with the series. However, as of 2025, the reality star is nearly unrecognizable. She stepped out in a blunt bob with a style that was more sophisticated than in her early days on "The Bachelor." Of course, with this change came whispers of plastic surgery. To be fair,Bristowe has been candid about some procedures she's had done, from breast augmentation surgery to blepharoplasty, so some of those changes are accounted for. The rest appears to be a sleeker upgrade. 

While Lizzo has been very open about her weight loss journey online, the star's epic style transformation has truly been a sight to behold. With new, luscious red hair, the singer has been stepping out in notably glamorous outfits, opting for a red carpet vibe that's top notch no matter the occasion. It seems she's experiencing these changes alongside a creative evolution. In September 2025, she referenced her interview with New York Magazine on Instagram, and wrote in the caption: "I'm in one of the most exciting, creative flows I've had as a human being on this planet." 

Ariana Madix first became famous for starring on Bravo's "Vanderpump Rules," but since then, she's become a well-known star in her own right. Madix's style has changed just as much as her career. In the early days, she wore her hair in long, blonde tresses and had a girl-next-door vibe about her. But by 2025, Madix took things to a whole new level. Madix has since grown out the bob she cut back in 2017 and now wears long, sleek hair with glamorous vibe. On Instagram, her looks are absolute show-stoppers, complete with sequins and sparkles. She's in her bejeweled era. 

Cameron Diaz is another celebrity who has completely changed up her look in 2025. It makes sense, because Diaz had other big changes happen in her life. In January, she returned to acting after a ten year hiatus with her Netflix film "Back In Action." Diaz shocked fans when she appeared at the Stella McCartney show in Paris in March 2025, her first fashion show appearance in over 13 years. She absolutely dazzled, revealing her new transformation. Diaz wore her hair in frosty, bleach-blonde face-framing pieces. She also wore a softer style of makeup to juxtapose her bold, cherry red look. It was soft glam at its finest.
