Former plus-size model Crystal Renn has transformed her look quite dramatically by changing her hair color from brunette to icy blonde.

Renn's runway career has taken a few twists and turns along the way, recently morphing from full-figured photo shoots to mainstream modeling in the latest Sport Illustrated swimsuit issue.

She talked about the new look, "People can't believe the transformation.  I had black hair and now I have white hair.  That's what's so exciting.  I wanted to do something different.  I wanted to show up as a different canvas at a shoot."

Crystal admits, "It's a very extreme look but very beautiful even though it's nothing conventional.  It's a challenging look but what's wonderful is it's something that photographs beautifully.  I'm not trying to conform to one certain look ... and that keeps life fun."

This does beg the question ... blonde? or brunette?
