'Gossip Girl' Stars Blake Lively and Penn Badgley Split'Gossip Girl' costars Blake Lively and Penn Badgley have split after three years together, a rep tells Us Weekly. The two ended their relationship in mid-September; they met as preteen actors in Los Angeles.

"They're professionals," an insider tells the magazine. "They're still good friends and hang out on the set."

Badgley, 24, told Us Weekly a year ago that the working/dating dynamic was no big deal. "Some would say it's a double-edged sword, but in our case, we manage to balance it well," he said.

Lively, 23, has added some major film work to her resume lately, featured in Ben Affleck's 'The Town' and starring alongside Ryan Reynolds in the upcoming 'Green Lantern.'
