Pretty reckless, indeed!

Taylor Momsen performed a very intimate show on Wednesday in Barcelona. The Pretty Reckless frontwoman, 17, straddled a female fan and gave her a lap dance mid-concert!

While Momsen wore a black sleeveless shirt, the recipient of her affection was clad in only a black bra.

The former Gossip Girl star doesn't shy away from controversy; just last month she flashed her bare breasts in concert, and once joked that she "f**ked a priest."

Tell Us: Was Taylor's performance edgy or over-the-top?
