The incredibly attractive, low-key celebrities have become a couple since March 2013 when they were seen in Boston. They admitted the blossoming relationship after nine months of exclusively dating, while the British model chaperoned the Cooper during his "American Sniper" premiere in New York.

Both remained tight-lipped about their relationship, but the 22-year-old model seemed to have a "boring" impression of her boyfriend.

"I don't talk about my boyfriend because it's boring," she told the magazine. "But we did meet at the Style Awards, I'll give you that. Look, maybe it's best for me to say, 'I'm not one of those girls who goes on about their boyfriends.' I do think whatever I say will sound weird. But 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 told Elle on February 2013.

Post-breakup, Cooper was seen partying in Vegas with Jonah Hill and Miles Teller, Wednesday night. The actor, according to insiders, was dancing all night.

No other details are made known regarding the cause of the split since they attended the Oscars together in February.

The 40-year-old actor, who was briefly married to "Crash" actor Jennifer Esposito, was planning to move-in with his "young" love when he came with the decision of fulfilling his West End dream, debuting later this year.
