Episode 3X5154 DAN DE FLEURETTE
It's the first day of school at Constance Billard which means it's also time for Jenny to take her rightful place as the new Queen Bee. Unfortunately for Jenny, Blair is more than happy to intervene when news reaches her that she may be needed back at Constance. Meanwhile, Lily returns home to Rufus and her family to find that things are definitely not as she left them. Plus, a famous movie actress, Olivia Burke (recurring guest star HILARY DUFF - A Cinderella Story, Material Girls, Lizzie McGuire), enrolls at NYU in hopes of having a somewhat normal college experience, and is assigned to be Vanessa's roommate. Guest star TYRA BANKS (The Tyra Show, America's Next Top Model) appears as Ursula, an actress co-starring in Olivia's movie and someone who Serena befriends.
