"American Sniper" actor Bradley Cooper has reportedly separated from his girlfriend Suki Waterhouse after dating the model for two years.

The couple is said to have grew apart due to their hectic schedule, reports aceshowbiz.com.

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 UK magazine.

`I'm not one of those girls who goes on about their boyfriends ... I do think whatever I say will sound weird. 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," she added.

Cooper was once married to actress Jennifer Esposito who tied the knot with British model Louis Dowler last year. He was also romantically linked to actress Zoe Saldana whom he dated on and off before seeing Waterhouse. Saldana is now married to Marco Perego.
