Paper Magazine and Express threw a party last night at fashion hot spot du jour Don Hill’s to celebrate the wrap of the brand’s Spring 2011 spring campaign and runway show. Never mind how Paper and Express make sense together (they don’t really)–Taylor Momsen’s band, “The Pretty Reckless,” performed. So we had to go.

The expectations for Momsen were high: She recently told Revolver that she likes a good sex tape but “wouldn’t fuck Tommy Lee,” so we were counting on her to do something obscene. And she didn’t disappoint. During “Make Me Wanna Die,” she caressed herself and then pulled down her low-cut shredded rock concert tee down to flash the audience. Don’t worry, her nipples were covered by duct tape x-es (it might have been electrical tape–either way, ouch). Which also means this was a premeditated move. Unless Tay just walks around with duct tape x-es over her nipples, which, considering her proclivity for stripper-wear, is entirely possible. Either way, I was a bit taken aback. I know she’s trying to be super punk rock right now but she is only 17. The models however, the ones who walked in the Express show earlier (including Jessica Hart, Eniko Mihalik, and Erin Heatherton), were completely unfazed. Probably because they’re all the around the same age as Momsen, have to get naked a lot for their work, and mostly because the handful crowded in front of us (we’re not sure which ones) were too busy smoking a joint.
