'Gossip Girl' star Taylor Momsen goes topless at Pretty Reckless show

Notorious pants-shunner Taylor Momsen is now tiring of another garment: her top.

The "Gossip Girl" star performed at New York club Don Hill's on Oct. 21, and while singing "Make Me Wanna Die," opted to pull down her shirt and flash and grope her strategically pastie'd bare chest.

Hollywood Life nabbed video of the stunt, and though you might think it might be the kind of thing to happen in a wild rocker moment, it was more of a subdued, calculated mini-flash.

Momsen was performing with her band Pretty Reckless at an event co-hosted by Paper Magazine and  Express -- and though this doesn't technically qualify as nudity, it should be kept in mind that she's still only 17.
