Pretty reckless may not do this girl justice!

Taylor Momsen performed a very intimate show on Wednesday in Barcelona, Spain, in which the 17-year-old singer and (former?) Gossip Girl actress straddled a female fan and gave her a lap dance mid-concert (here's a pic)!

While Momsen wore a black sleeveless shirt, the recipient of her affection was clad in only a black bra. She's certainly no stranger to controversy, but hey, it's working out for her.

Here's hoping for a Jenny cameo at some point soon ...
