Willa Holland

Gossip Girl isn't the first program in which Willa Holland has played a rebellious teen; she is most famous for her role as Kaitlin Cooper on The O.C. Long before that, Willa was a top child model. When she decided to give acting a try, she was able to consult some expert advisers: her mother is an actress and her stepfather is director Brian De Palma. De Palma found Willa an agent at the suggestion of Steven Spielberg, a family friend. Agnes, her Gossip Girl character—a crazy model—only featured in a few episodes of the second season, but she certainly stirred up plenty of drama for little Jenny Humphrey.
