Sean Penn and Robin Wright took 'quite a while' to become friends after divorce

***DIGITAL USE ONLY*** The celebrity couple ended their 14-year marriage in 2010. They'd been together since 1989. "It turns out it's a lot quicker to repair a friendship after divorce if there are not kids involved," he said in an interview with The New York Times. "It took Robin and I quite a while. There was a lot of drama." He added, "Much more important to repair it if there are kids involved, but no easy swing, right?" The couple share two children, Dylan, 33, and Hopper, 30. Last year, the former partners were seen hanging out with each other several times.
