Transformation

"I live in my dark makeup," Taylor Momsen once told us. She wasn't kidding! She may have joined the cast of Gossip Girl with blond beachy waves, but as the lead singer of The Pretty Reckless, the 19-year-old contrasts her platinum extensions with pitch-black liner and lots of it. The look seems to be working—this year alone, Momsen has been named the face of both Madonna's Material Girl clothing line and John Galliano's upcoming fragrance. Rock on, Taylor!
