Katie Cassidy and Chace Crawford's Steamy Liplock

Spending the day on the set of “Gossip Girl,” Chace Crawford and Katie Cassidy were all eyes for each other in New York City on Thursday (August 26).

With Miss Cassidy flashing her undies, the young Hollywood hotties shared an intimate kiss while sitting on a park bench in the Queens area of the Big Apple.

Meanwhile, season three of the hit CW show is now available on DVD and mainly focuses on Jenny Humphrey's development and how her experiences, wants and needs seem to mirror Serena's pre-series life.

Some notable guest stars that joined the “Gossip Girl” cast last season include Hilary Duff, Tyra Banks and Billy Baldwin.
