SERIEKILLER

Seems like on-set sources, which the pubs tell us are reliable, have told each paper that Chace Crawford and Gossip Girl co-star and real-life roommate Ed Westwick are in a relationship and not trying to hide it, at least on set.

BOTH NY papers tell us that Chace and Ed were recently seen kissing, open-mouthed on set (in Chace's trailer).
