Taylor Momsen: Not a Girl, Not Yet a Woman

We admit we have a rather unhealthy obsession with Taylor Momsen, the 15-year-old actress who will likely do the bulk of her growing up on CW's Gossip Girl. (If Josh Schwartz's first show, The O.C., is anything to go on, Gossip Girl will likely be on the air for about four seasons, by which time Ms. Momsen will be safely post-high-school age.)

But the young Ms. Momsen has already embarked on the fast track to image makeover, trading in her pink tutu dresses for '80s rock star hair, leather pants and motorcycle jackets. All of which makes us wonder if the young actress is in desperate need of a stylist. Click below for a slideshow chronicling Ms. Momsen's seemingly drastic transformation from the day she arrived at the CW Upfronts in 2007 to the raccoon-eyed, biker chic look she unveiled during New York Fashion Week.
