Move over, Margherita. There's a new family ingenue in town. Actress Jennifer Missoni, daughter of Luca, will star in three Gossip Girl episodes this February, as well as Playback, a soon-to-be released film starring Christian Slater. We love the Missoni women--each generation is as glamorous as the next--so we're excited to see what Jennifer is capable of. Tune in February 14 to see her Gossip Girl debut, where she plays Donna, a character "very serious about her job." We're assuming it has something to do with Fashion Week?
