Is Ed Westwick available for private bookings at bachelorette parties?

The actor -- naughty as Chuck Bass on Gossip Girl -- gave an impromptu striptease at a recent Milwaukee, Wisc. wedding reception.

As a TMZ photo testifies, the 22 year-old star got into the celebratory spirit on the dance floor, unbuttoning his shirt down to the navel.

Enjoying the show? The cheering bride (reportedly a buddy of Jessica Szhor, Westwick's costar and girlfriend) and a male guest -- who looks like he's about to plant a wet one on the actor's upper chest.

No biggie for Westwick: the rakish actor recently made out with his first guy onscreen in an Oct. 19 episode of Gossip Girl.
