They're pretty, they're young and hot damn are they dirty! The Gossip Girl cast, known for their scandalous characters, recently struck some super sexy poses for Rolling Stone.

Go behind the scenes with the Upper East Siders as they let loose in a pillow fight and jump between the sheets for their close-ups.
