"He's like the master of it with Gossip Girl. They make out with each other all the time," Olsen recently told E! News.
Like a true gentleman, Crawford, 26, didn't take their onscreen kiss to the next level. "Chace is a good guy," Olsen explained. "He's very southern."
In addition to Olsen and Crawford, Peace, Love, & Misunderstanding also features Jeffrey Dean Morgan, Jane Fonda, Catherine Keener, Rosanna Arquette and Kyle MacLachlan.
