Hilary Duff and Penn Badgley caught kissing in New York City! Omg, I hope his girlfriend Blake Lively didn’t see this. Oh what about Duff’s beau,NHL hockey player, Mike Comrie, bet he wouldn’t like this. Ok, they two are working on the set of “Gossip Girl” but they sure look like they are really loving the smooch, don’t they?

Penn Badgley and Hilary Duff get down to work on the set of “Gossip Girl“. The couple shot a scene where Hilary’s character, Olivia, kisses Penn’s character, Dan. By the look of the smile on Hilary’s face when the scene was over, she isn’t finding her role too tough to play!
