Renee Zellweger
Though she's never specifically admitted to anything, the actress has discussed her new appearance. "I'm glad folks think I look different!" She told People in October 2014. "I'm living a different, happy, more fulfilling life, and I'm thrilled that perhaps it shows."
However, she added, "It seems the folks who come digging around for some nefarious truth which doesn't exist won't get off my porch until I answer the door."
Michael Jackson
Perhaps one of the most dramatic changes of all was the King of Pop. However, he continued to deny having plastic surgery with the exception of his nose, which he said "helped him breathe better."
Lara Flynn Boyle
The actress stepped out in 2013 looking like a different person than she did at the start of her career in the '90s. However, she has stayed mum on the subject.
Heidi Montag
The former Hills star has been very open about her many plastic surgeries. "I am absolutely beyond obsessed," she told People magazine after getting her nose job, a boob augmentation, a brow lift, injections in her lips and cheeks, a chin reduction and liposuction.
Janice Dickinson
The model has previously revealed that she "lives for plastic surgery." She has admitted to having a tummy tuck and a face-lift. She also does Botox and Restylne.
Melanie Griffith
The actress looks like a completely different woman today than she did at the start of her career in the early '70s. However, she's continued to argue that she's never gone under the knife.
Iggy Azalea
After getting a boob job and a nose job, the female emcee said, "There are things that I didn't like about myself that I changed through surgery. There are other things I dislike but I've learned to accept. It's important to remember you can't change everything. You can never be perfect."
Courtney Love
The singer and former wife of the late Kurt Cobain has admitted to getting a nose job as well as a face lift, and she says she regrets none of it! "I was an actress in the '80s but, well, let's just be real, I had a really big nose," she said during and interview with Jimmy Kimmel. "That schnoz was not taking me anywhere but radio."
Vicki Gunvalson
The Real Housewives of Orange Country star decided to make a change in 2012 after being compared to Miss Piggy. "I did some cartilage reconstruction on my nose," she said on the show at the time. "I had some fat injected in the upper part of my cheeks so I don't have any more wrinkles. And I did a little chin implant."
Donatella Versace
