The world could not stop talking about the chemistry Bradley Cooper and Lady Gaga shared both on and offscreen while promoting A Star Is Born, and so when news comes out that the actor and his longtime girlfriend Irina Shayk are having problems, eyebrows immediately start to rise. But cool your jets, Internet, the couple has reportedly been going through a rough patch for a while now.

"Bradley and Irina have been unhappy in their relationship for some time and have tried to make it work," a source told Entertainment Tonight. "They both want the best for their daughter [Lea De Seine , 2], but seem to be coming to terms with the fact that staying together might not be for the best."

However, the source assures that Cooper's relationship with Gaga has nothing to do with it.

"Things were difficult before Bradley started filming A Star Is Born but his dedication to his work while making the movie only made things harder at home," they said. "The constant speculation about Bradley's relationship with Gaga -- while things were difficult at home -- didn't help the situation. But his relationship with Gaga is not the issue. They have many daily issues as parents and as professionals and have been fighting."

"Their troubles have been going on for quite some time and they even considered splitting during the release of the movie," the source continued. "They talked things through a great deal and seemed to hold off and keep up appearances for the time being. It was recommended they delay a split at what seemed to be the peak of his career because the negative attention would take away from the excitement of the release."

Though they're still together, the source says a split is a real possibility. "Bradley and Irina are trying to work it out, and their friends are still holding out hope, but it doesn't look good and friends are concerned [the relationship] won’t last," they said.
