A lot can change in a public figure’s life over the years. New roles, health journeys, training plans, and personal choices can reshape how someone looks from one chapter to the next. The camera catches everything, which means fans often notice every haircut, gym milestone, and style shift.
This roundup looks at well known names who have undergone major transformations that people still talk about. You will find facts about what they changed and why, from role specific preparation to public health disclosures to evolving fashion and beauty choices. It is a reminder that careers evolve and so do the people living them.
Zac Efron
Efron has explained that a serious facial injury in 2013 and the recovery process changed his jawline. He described breaking his jaw and explained that his masseter muscles worked overtime during rehab, which affected his appearance over time. He has continued to address the topic openly in interviews.
Alongside the injury recovery, Efron has cycled through intensive training for roles that required a bigger frame. Projects that asked for lifeguard level conditioning and action ready builds pushed him into strict nutrition and gym routines, then back out once filming wrapped.
Adele
Adele began a structured fitness plan after touring and has credited regular strength work and cardio for a significant drop in weight. Trainers and a consistent schedule helped her build endurance for shows and improve overall health away from the spotlight.
Her public appearances have since shown a new styling approach with different silhouettes and stage looks. She has also spoken about the mental health benefits of training, noting better energy and performance during long recording and promotional cycles.
Jonah Hill
Hill’s weight has changed across the years as he adjusted diet and exercise between comedy roles and more dramatic parts. He has discussed working with nutrition professionals, cutting back on certain foods, and building a routine that fits a busy filming calendar.
He has also changed his style, growing out his hair and beard at various times and experimenting with fashion. These choices, together with fitness changes, have made his look vary a lot from the early comedy era to recent directing and acting work.
Kelly Osbourne
Osbourne has spoken candidly about undergoing gastric sleeve surgery and building new habits around diet and exercise. She has described regular workouts and a focus on wellness that helped sustain the change long after the initial procedure.
Her style has shifted as well, with updated hair colors and a more tailored wardrobe for television and red carpet appearances. The combined effect makes her current look very different from her early reality TV years.
Christian Bale
Bale is known for dramatic body changes to meet the demands of specific roles. For one project he dropped to a very low weight, then quickly rebuilt muscle for a superhero film, and later gained weight again for a political biopic. That pattern reflected the physical intensity of his character preparation.
These shifts happened under medical supervision and tight schedules that aligned with production timelines. Bale has noted that returning to a baseline after each role required careful planning, which explains the wide differences from film to film.
Chris Pratt
Pratt transitioned from a softer build during his sitcom years to a leaner, muscular frame for a blockbuster space adventure. He has credited rigorous training, calorie tracking, and structured hydration as the core of that transformation.
He has maintained much of the conditioning with ongoing gym work between films that call for stunts and superhero level movement. This long running approach has kept his look closer to his action roles than to his early comedy days.
Mickey Rourke
Rourke boxed professionally after early acting success and later returned to movies. Years in the ring and subsequent reconstructive procedures changed his facial features in visible ways. He has spoken about surgeries to repair damage and about the results that followed.
His career comeback featured a highly praised wrestling drama that brought him new attention. With that return came updated grooming and wardrobe choices that embraced a different image from his 80s leading man period.
Renée Zellweger
Zellweger stepped back from acting for several years, then returned with a new public profile that sparked conversation about her look. She has said she was healthy and rested and chose to focus on work she found meaningful after the break.
Her acclaimed performance as Judy Garland reminded audiences of her range and marked a fresh chapter in her career. With new roles came updated styling on carpets and in press, which added to the sense of change since her early romantic comedies like the ones led by her Bridget Jones character.
Val Kilmer
Kilmer underwent treatment for throat cancer and later lived with a tracheostomy, which affected his voice and appearance. He documented parts of this journey in a self reflective project that used decades of personal footage.
His legacy includes major films from the 80s and 90s such as ‘Top Gun’, ‘The Doors’, and ‘Heat’. Recent appearances have honored that history while accounting for health considerations, which explains why viewers notice a pronounced difference from his earlier years. Unfortunatelly, he passed away at April 1, 2025.
Brendan Fraser
Fraser experienced injuries during peak action years and has discussed multiple surgeries that followed. His later return to high profile roles came with a different physical presence shaped by time away from action sets and by recovery.
His leading role in ‘The Whale’ used extensive prosthetics and special effects to portray the character. Off screen he has kept a lower key style than his 90s adventurer image from films like ‘The Mummy’, which makes the contrast even more noticeable.
Kylie Jenner
Jenner has acknowledged using lip fillers and has experimented with makeup and hair that shift her look frequently. The changes were documented across reality television and social platforms, giving viewers a clear timeline of her beauty evolution.
Her brand work involves frequent photo shoots and campaigns that introduce new aesthetics. That constant reinvention with contour techniques, wigs, and fashion styling can make her look very different from one season to the next.
Khloé Kardashian
Kardashian has said she had a nose job and has shared her fitness routine in interviews and on television. She also fronted the series ‘Revenge Body’, which focused on training and wellness, and reflected her own commitment to gym centered habits.
Her style has moved toward sleek hair, body contouring outfits, and bold beauty looks for red carpets and business events. This sustained focus on fitness and fashion has created a look that differs a lot from early seasons of ‘Keeping Up with the Kardashians’.
Linda Evangelista
Evangelista shared that she experienced a rare side effect after a cosmetic fat reduction procedure. She later returned to the public eye with major fashion covers and campaigns that addressed her story directly.
Her comeback involved careful styling and lighting that supported her comfort while showcasing her legacy status in modeling. With time she also appeared in runway moments and brand projects, marking a new stage that looks distinct from her 90s supermodel era.
Kumail Nanjiani
Nanjiani trained extensively for a superhero film and credited professional coaches and nutrition planning for the change. He documented progress photos and talked about the discipline required to reach a physique suited to the role.
After the shoot he balanced maintenance with other projects that did not require the same size. The result is a look that can swing between athletic builds depending on current filming needs and recovery windows.
50 Cent
The rapper and actor lost a large amount of weight for the football drama ‘All Things Fall Apart’. He spoke about liquid diets and dedicated training to meet the demands of the role, then returned to a healthier baseline after production.
In later years he took on producing and acting work in television that kept him in the public eye with a different style than his early music videos. Changes in grooming and wardrobe for red carpets and set visits add to the contrast with his debut era.
