Spotted: Leighton Meester aka Gossip Girl's Blair Waldorf at a Grammys after party in Los Angeles, "surrounded by a cloud of funny-smelling smoke. " The 21-year-old actress seems to have a penchant for smokin' joints, if this and this past November's incidents are any indication. I guess this sort of makes up for the totally-scaled-down-from-the-books drug use on the show (which is coming back in April!) Now if we could just get her to shave Vanessa's head, frizz out Jenny's hair, and, well, make Dan gay! [NYP] After the jump, an episode clip of Blair's friend Serena (Blake Lively) totally doped out and having a cutsie water fight.
