Next season's "Gossip Girl" casting just keeps getting better! First, we heard that Joanna Garcia was joining the show as a love interest for Nate. Now, Entertainment Weekly reports that one-time teen mega-star Hilary Duff will get a multi-episode arc as well!

According to EW, Hilary will play Olivia Burke: a movie star who pulls a Natalie Portman/Claire Danes and enrolls in NYU (along with the majority of our "Gossip" gang) in the hopes of experiencing real college life. And! She'll be rooming with none other than Vanessa (Jessica Szohr), which leads us to believe it's time for Dan Humphrey to fall for another lady who's WAY out of his league.

Hilary's "Gossip Girl" debut will be in the season's fourth episode. We can't wait!

What kind of trouble do you think Hilary's character will create? And who will be her love interest?
