Bradley Cooper and girlfriend Suki Waterhouse have not given any comments yet about their rumored to split after two years of dating, but the "American Sniper" actor was reportedly not affected by the breakup.

E! News' Marc Malkin claimed that he can definitely say that the news about the split-up of the 40-year-old American actor and producer and 23-year-old English actress and model is true.

"I can exclusively reveal that the couple of about two years have called it quits," the entertainment writer shared.

However, he noted that whether Bradley Cooper and girlfriend Suki Waterhouse's breakup is permanent or not is still everybody's guess.

"Whether or not it's permanent is anyone's guess right now, but Waterhouse, 23, did attend the Oscars just last month with Cooper, 40, who was nominated for his work in American Sniper. (His mom was also with them.)," the E! story read.

The "Aloha" actor and the "Love, Rosie" actress were first romantically linked to each other in March 2013 when they were seen together in Boston.

"They made their Hollywood debut as a couple after nine months of dating when the British model-actress was Cooper's date to the New York premiere of American Hustle in December 2013," the report said.

After a month, Suki Whitehouse was spotted as Bradley Cooper's date during the "Screen Actors Guild Awards" in Los Angeles.

In an earlier Elle U.K. interview, model Suki Waterhouse opened up about her relationship with Bradley Cooper.

"I don't talk about my boyfriend because it's boring. At least, that's what I decided to tell you when you asked. 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?" said Suki Waterhouse.

But despite the reported split, Bradley Cooper seems to be doing just fine as he was spotted partying in  Las Vegas on Wednesday. The "American Sniper" actor was seen with friends Jonah Hill and Miles Teller.
