Penn Badgley & Hilary Duff: Kissing Couple

Hilary Duff and Penn Badgley share an on-screen kiss while on the New York City set of Gossip Girl on Wednesday afternoon (August 26).

Looks steamy!

In the books, Dan Humphrey (Badgley) attends Evergreen State College in Washington but in the series, he attends NYU. Olivia Burke (Duff) is a movie star who also enrolls at NYU in search of a traditional college experience. She ends up rooming with Vanessa (Jessica Szohr).

FYI: Penn is wearing Nooka‘s “Zub Zoo 38″ watch in Deep Blue.
