The Gossip Girl cutie was returning from the Teen Choice Awards, where the cast picked up six surfboards, including Choice TV Show Drama.
At the Teen Choice Awards, Leighton spoke to Access Hollywood about the racy and controversial ad campaign for Gossip Girl.
“It’s mature, but I feel like it speaks to kids and it doesn’t white wash anything,” Leighton said.
“We just end up seeing it on a billboard somewhere,” she said. “But I think that it’s smart and it’s fine and it’s cool.”
