After dating for two years, PEOPLE is reporting that Bradley Cooper and Suki Waterhouse have split.

The American Sniper star is notoriously private when it comes to his relationships, and the couple have tried to stay below the paparazzi radar as much as possible — although Suki did open up a bit in a 2013 interview with Elle U.K. “I don’t talk about my boyfriend because it’s boring,” the British model-actress explained. “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?”

There’s been no official confirmation or denial from either Bradley or Suki, although Suki’s London rep Katy Moseley simply stated, “No comment.”

According to PEOPLE, a source close to the couple says they broke up before the Oscars, but remained on friendly terms and attended the award show together. The night after the Oscars, the couple was spotted having dinner at Nobu Malibu, “though an onlooker says they didn’t seem affectionate during the meal”;

Meanwhile, Bradley spent last night in Vegas to check out Elton John’s performance at Caesar’s Palace, and then hung out with Sir Elton, 22 Jump Street“s Jonah Hill, Whiplash star Miles Teller, musician Brandon Flowers and U.K. comic Jimmy Carr.

What happens in Vegas stays in Vegas — unless someone takes a photo and tweets it:
