Crystal Renn walked the red carpet of the ninth annual New Yorkers for Children spring dinner dance on April 10 with a new look, sporting platinum blonde hair and eyebrows in a Zac Posen gown.
In the photo above, Renn can be seen before getting her blonde hair at the Sports Illustrated Swimsuit launch party in New York, Tuesday, Feb. 14, 2012.
"People can't believe the transformation. I had black hair and now I have white hair," Renn told People magazine in a recent interview. "I wanted to do something different. I wanted to show up as a different canvas at a shoot. It's a very extreme look but very beautiful. Though it's nothing conventional."
"It's a challenging look. But what's wonderful is it's something that photographs beautifully," she added.
The 25-year-old model, who is 5 feet 9 inches tall, started modeling at 14. She once suffered from anorexia and later returned to modeling, after getting healthy and gaining weight, as a plus-size model. In 2010 Renn was spotted out with a slimmer figure.
She explained the change to New York Magazine's fashion blog, The Cut, in an interview in October 2011.
"About a year and a half ago, I had a lot of personal things going on," Renn said, perhaps referring to her divorce in 2009. "And I went hiking and I wanted to get my [expletive] together. I wanted to take care of myself."
"It had been eight years since I'd worked out. I'd suffered an eating disorder and I used to exercise eight hours a day. But I'd recovered," she added. "It's time to change things, to give it a chance again. I guess you could say that through my life changes and what was going on, I wanted to make some changes in my life and taking care of my health was one of them."
Renn also wrote a book titled "Hungry: A Young Model's Story of Appetite, Ambition and the Ultimate Embrace of Curves" which was published in 2009. Renn modeled for this year's Sports Illustrated swimsuit issue and told People magazine in February, "I have been a double-zero to a 16 even, for a bit...Now to settle at a [size] six or an eight, it's a really interesting place to be, because there are very few sixes or eights."
