Bradley Cooper is single again. The "American Sniper" actor has reportedly separated from his girlfriend Suki Waterhouse after dating the model for two years. According to Us Weekly, the couple grew apart due to their hectic schedule.

Cooper, 40, started dating Waterhouse in 2013. They had never been shy to show their affection to each other, but they rarely discussed their relationship in interviews. "I don't talk about my boyfriend because it's boring," Waterhouse once told Elle U.K.

"I'm not one of those girls who goes on about their boyfriends ... I do think whatever I say will sound weird," she explained. "The truth is, if I start talking about him, I probably won't be able to stop. And I don't really want to talk about him, you know?"

Bradley Cooper was once married to actress Jennifer Esposito who tied the knot with British model Louis Dowler last year. His other ex Zoe Saldana whom he dated on and off before seeing Waterhouse is also now happily married. She has twin sons with husband Marco Perego.

"I consider myself to be a romantic," Cooper once said in 2013. "I love the company of a great woman. I think a relationship works best when both partners have a certain ease in the way they relate to each other and there's a level of harmony that goes beyond just physical attraction."
