Spotted: Lonely Boy chatting with Mystery Girl…

Wait!! That’s no mystery girl.. That’s Hilary Duff!!

We spotted Hilary Duff on the set of Gossip Girl filming in New York City yesterday. Hil is set to play Olivia Burke.. a famous movie star who enrolls in NYU hoping to have a "normal" college experience and ends up rooming with Vanessa (played by Jessica Szohr) for their freshman year. And.. for those of us who watch Gossip Girl regularly.. we know that there is nothing "normal" about these Gossipers lifestyle! Good luck Olivia!

Can’t wait until the new season starts on September 14th (write it down!)

Judging by the pics below.. it looks to me that sparks are flying between Olivia and Daniel Humphreys.. I wonder how S is going to feel about this one.. XOXO GG!
