Bradley Cooper and Irina Shayk separate a few days after co-star Lady Gaga ends his engagement

The relationship between Bradley Cooper and Irina Shayk ended just days after the separation of Lady Gaga and her fiancé.

Fans pointed out that the two romances were disintegrated publicly a few hours after a flash advertising tour with A Star Is Born.

Rumors were circulating about Bradley, 44, and about Irina's four-year relationship for months.

Speculation about Lady Gaga, 33, and the actor spread like wildfire after the hot Oscar performance of the hit song Shallow.

Model Irina, 33, shares a four-year-old daughter, Lea De Seine Shayk Cooper, with Bradley.

Singer Gaga is separated from fiancé Christian Carino, 50, after throwing a ring on it last year.

Gaga was forced to deny a relationship with Bradley after this wild performance of the Oscars.

Addressing Jimmy Kimmel, Lady Gaga said, "First and foremost, social media is quite frankly the Internet toilet and what he did to pop culture is catastrophic.

"And people saw love, and guess what, that's what we wanted you to see. It is a love song, the film is a love story. "

A source close to Bradley and Irina told People.com that they "spent a lot of time on the sidelines," before confirming that their four-year relationship was over on Thursday.

They went on to say that Cooper, who had been nominated for an Oscar for A Star Is Born, "was living totally separate lives," Shayk said at the time they called the time they had together.
