When the two Gossip Girl actors hooked up off , they kept their relationship quiet out of fear of what their bosses on the show would say. “[But then] we were like, ‘Oh no, that’s exactly what they want,’” Lively, 33, who’s now married to actor Ryan Reynolds, revealed. “They wanted us all to date… it fed their whole narrative.”

Lively and Badgley, 34, broke up in 2010 but didn’t tell coworkers as they continued working together. “I don’t know how they did it,” co-producer Joshua Safran said. “They kept it from everybody, which is a testament to how good they are as actors.”
