Question: So what's going down on The O.C.? I need some major [scoop].

Answer: After an exhaustive search, producers have tapped 14-year-old Willa Holland to play Marissa's bitchy younger sis, Kaitlin. She'll debut in early '06. Fans of HBO's The Comeback will no doubt recognize Holland as Franchesca's pal, Kalla. Oh, how I miss my Valerie.
