Gossip Girl's Jessica Szohr, 25, admits that she's tempted to steal her co-star Taylor Momsen's wardrobe on set in the September issue of Nylon.

Vanessa's waaaay too much with every color and pattern," the actress tells the mag. "It sounds like I’m being negative about them all, but I'm not. I think they all look great. But if I was going to go shopping for [me], I'd head straight into Jenny's closet." [Just Jared]
