Suki Waterhouse is embarrassed that Bradley Cooper has moved on with Irina Shayk.

The 23-year-old actress, who split from the 'American Sniper' star in March after more than two years of dating, is reportedly very upset he has been spotted passionately kissing the Russian model in London and New York City in recent weeks, because she hoped they could rekindle their romance.

A source said: ''Bradley kept his relationship with Suki kind of open-ended when they broke up. Even if he's not back with Suki, people think they still hook up, so it's embarrassing to her that he's running around town with Irina.''

But the 40-year-old actor doesn't care what anyone thinks about his new relationship.

The insider told Life&Style magazine: ''Bradley loves models, and they love him.''

Another source told Star magazine: ''He has insane chemistry with Irina. He's never been so physically attracted to a woman.''

The couple were introduced by mutual friend Leonardo DiCaprio shortly after Bradley split from Suki.

A friend previously said: ''Bradley was very taken with Irina when he first saw her at the Oscars in February. He and Suki were on the rocks and, once they'd split, Leonardo introduced him to Irina.''
