Rufus had better start shopping around for a cute designer shock collar to place on unpredictable Jenny Humphrey, 'cause it looks like Little J is going to be dabbling even deeper into the dark side this season.

According to several inside sources, a deal closed a few hours ago for Willa Holland, best known as Kaitlin Cooper on The OC, to come on board the cast of Gossip Girl in Season 2 for three episodes.

She'll play Agnes, a 16-year-old model who meets Jenny while working for Blair Waldorf's badass fashion designer mother, Eleanor Waldorf, and is supposedly anything but a good influence. Thoughts?
