Gossip Girl‘s Taylor Momsen, who lately already looks like she’s with the band, revealed some rock star goals at the opening party for the Manhattan Rock and Roll Hall of Fame Annex on Mercer Street last night.

Page Six reports that Momsen, who plays burgeoning bad girl/fashion designer Jenny Humphrey on the CW’s rich bitch fest, “looked just like a rocker and kept talking about her band,” a source said as Momsen rocked out to Blondie.

Other guests as the party included Molly Sims, Olivia Palermo, and guitar legend Les Paul who reportedly flipped off reporters. RAWK!

Momsen is 15, and already on her way to being an NYC bad girl type. Shag haircut, party hearty, and a cigarette in her maw. All she needs is to stand with one leg on a monitor, wearing a short skirt with no drawers on and shredding a guitar during a show and she’s got it down pat. Courtney Love can give her some tips.
