Is it just me or has Lily gotten herself in quite a bit of trouble with the Gossip Girl gang? Well perhaps she'll look to her older sister Carol for some advice. Check out the spoilers on the first appearance of Lily's sister on Gossip Girl!
Look to meet Lily's older sister Carol in early April when she rolls into the Upper East Side... and according to TV Line's Ausiello, she won't be rolling in alone. Carol will be played by Ghost World's Illeana Douglas.
