Crystal Renn Goes Blonde! (PHOTOS, POLL)

When most ladies go blonde (via wig or highlights), they usually still look like themselves. (See: Vanessa Hudgens, Kim Kardashian, Katy Perry, etc.)

But when we saw model Crystal Renn's new bleached-out 'do, we were seriously shocked. Girlfriend doesn't look anything like herself!

Renn, who made her name as a plus-size model but recently talked about how losing weight affected her career, took a sunny vaycay to The Cove Atlantis in the Bahamas this weekend and enjoyed a private session swimming with dolphins.

Cute dolphins aside, it was Renn's new mane that made us do a double take. Not only have Crystal's brunette locks been shell-shocked with peroxide, but her eyebrows received the blonde treatment too. She's barely recognizable!

Crystal went blonde previously for the cover of W Korea in February, but that time, it was definitely a wig. This appears to be her bona fide Paris Hilton-hued hair.
