We’ve come to expect Gossip Girl’s Taylor Momsen to be scantily clad while performing with The Pretty Reckless but homegurl was straight-up trashy at Bamboozle Music Festival. In tiny denim cut-offs, a cropped tank, exposed roots, and far too much eyeliner, the 16-year-old looked too “rock star” for her own good. Momsen hates comparisons to Courtney Love, but she’s not doing much to distinguish herself as anything but a leggy, bleached party girl. Clean up your act, lil J!  [Photo: Splash News]
