Everyone looks different with age, and that includes Hollywood's most beautiful people whose looks have often been made worse by dodgy plastic surgery and years of hard partying. On the other hand, some celebrities make our list for self-imposed reasons. For instance, Rose McGowan of Charmed fame went as far as to shave her hair!
With that said, here are 17 stars- including McGowan- who are almost unrecognizable, but still incredibly beautiful!
1. Lara Flynn Boyle
Making a name for herself as Donna Hayward on the supernatural tv series Twin Peaks, Boyle refused to come back for the highly-anticipated third season, not that fans would have recognized her.
She is still a beauty, of course (just look at those eyes), but it would be hard to pin her face to her famed character.
2. Uma Thurman
After being a fashion model and then one of Hollywood's best-paid actresses, it must be incredibly hard to grow old gracefully and let go of the image that made you incredibly successful, but Thurman seems to be coping.
Despite entering the twilight stage of her career, Thurman's looks are taking on a different kind of beauty.
3. Meg Ryan
Meg Ryan made a name for herself in a string of Nora Ephron movies in the 1990s and was for years heralded as one of Hollywood's most beautiful woman.
Now sporting some face fillers, we can't help but think that it takes away the gloss of Ryan's natural beauty.
4. Jaleel White
Steve Urkel from Family Matters has changed a lot! For a start, he looks much less nerdy and has since starred in shows like Boston Legal, House, Psych and Dancing with the Stars.
Basically, it's the show has-beens appear on when their careers finally tank. But hey, White still looks pretty fly!
5. Kenny Rogers
After selling 120 million records worldwide with hits like the "The Gambler" and "Islands in the Stream" a dashing crooner like Rogers may be a shadow of his heartthrob days, but he's rocking the silver fox look to a tee.
You go, Kenny!
6. Renee Zellweger
The Bridget Jones star baffled photographers when she showed up to an event a couple of years ago looking completely different.
While her face seemed refreshed, it also looked nothing like the Zellweger of old, and the Internet was awash with speculation as to what it was the actress had actually done to her appearance.
7. Mickey Rourke
One of the most handsome men working in Hollywood in the 80s and 90s, Mickey Rourke made women weak at the knees in films like 9 1/2 Weeks and Angel Heart, but then a falling out with Hollywood and an ill-fated boxing career destroyed his career in more ways than one.
Not only did he royally annoy studio execs, but his pretty face was all-but destroyed, and it's taken years of plastic surgery to get this stud back into Hollywood.
8. Faye Dunaway
Faye Dunaway made waves in classic films such as Chinatown and Bonnie and Clyde, and her looks were just as noted as her acting chops.
In recent years, however, Dunaway's looks have come under the cosh after the star's lips looked abnormally large. You're a graceful starlet, Dunaway; you don't need fillers!
9. Haley Joel Osment
The first film that probably springs to mind when you recognize Osment is the Sixth Sense. He was the kid who told us he saw dead people, which is a pretty disturbing line for a child actor. Anyway, Osment's career- like many child stars- eventually dried up, and things got so bad he was even cast in the ill-fated Entourage movie- not that you'd have noticed.
Looking nothing like his younger days, Osment, while sporting a much healthier appearance than most washed-out has-beens, still bears little resemblance to the kid who saw dead people.
10. Elisabeth Shue
After wowing critics in pathos-driven films like Leaving Las Vegas and the cult classics Back to the Future Part II and Part III, Shue went off the map and has only recently started doing a bit more television work.
However, having taken such an extended break, many viewers probably wouldn't recognize her.
11. Ethan Suplee
After making a name for himself as a white supremacist in the powerful and evocative American History X and as Earl Hickey's ditzy younger brother in My Name Is Earl, Leonardo DiCaprio's buddy has lost a considerable amount of weight.
You could even say he now looks more like a leading man than the guy who always gets friend zoned in Leo's entourage.
12. Macaulay Culkin
Once America's richest child star, the actor attained wealth so early in his life that he could afford to divorce his parents! He shot to fame at the age of 10, six years after beginning his acting career and starred in several blockbuster movies.
The subsequent years were less successful and were riddled with addiction and the break-up of his long-term girlfriend, Mila Kunis. Less cherubic looking but considerably healthier, Culkin occasionally crops up in ads and cameos to earn a little 'pocket money' but the Home Alone star, who is worth an estimated $15m, admitted that his wealth takes him wherever he pleases. "I'm a man in his mid-30s who's essentially retired. I kind of go where the wind takes me a little bit."
13. Rose McGowan
The Charmed actress is now a prominent activist and campaigner for LGBT rights, which may explain why she decided to do away with her Hollywood image.
Ridding herself of the brunette locks that made her so recognizable in Hollywood, McGowan now rocks a shaved head and was one of the leading voices in bringing down Harvey Weinstein.
14. Frankie Muniz
The Malcolm in the Middle star was one of America's best-paid child stars when he starred alongside Bryan Cranston in the much-loved family comedy Malcolm In The Middle and also appeared in several Hollywood movies, earning him enough to retire from the screen and live a life of leisure.
Unfortunately for Muniz, his career tanked soon after the show finished, and after briefly pursuing a career as a racing driver, a much older looking Muniz returned to television sets on the reality show Dancing With The Stars.
15. Brigitte Bardot
An icon of the 50s and 60s, the original blonde bombshell possessed a beauty that was in keeping with the often overused term 'other-worldly.' Taking away her clear-to-see beauty, Brigitte Bardot oozed class as well as confidence, and her status as a sex symbol in the early 1950s gave her superstardom unheard of for non-English artists at the time.
One journalist, writing an article for Life Magazine in 1958 entitled, "The Charged Charms of Brigette," even gushed, "Not since the Statue of Liberty has a French girl lit such fires in America."
Since retiring from acting at 39, she has devoted the rest of her life to animal rights charities and at 83-years-old, has taken on an altogether different image.
She has also published five books and has controversially become an outspoken critic of Islam.
16. Lil Kim
In her heyday, Lil' Kim was one of the most fierce rappers out there after being discovered by the Notorious B.I.G., but if we're honest, the rapper has gone over the top with the plastic surgery.
You're a beauty Kim, but have you ever heard of the mantra; less is more?
17. Pete Burns
The late Pete Burns was very much a one-hit wonder when his band Dead or Alive found fame in 1985 with the song You Spin Me Round. A celebrated performer with a unique on-stage personality, the star's later years saw him the public eye for his work as a reality star on Britain's Celebrity Big Brother.
Perhaps in a bid to remain relevant, Burns underwent extensive plastic surgeries, much to the fascination of the media who couldn't help but report on his ever-morphing aesthetic. Burns passed away penniless following his costly obsession with plastic surgery.
