Actor Bradley Cooper says he has "made a friend for life" in singer-actor Lady Gaga after filming "A Star Is Born". "I made a friend for life. As great as this movie was, the thing that I think I'll take away forever is the relationship I have with her because she is an incredible person," people.com quoted Cooper as saying.

"I'm very lucky to have worked with her," he added. When it came to meeting her for the film, Cooper visited the pop star at her home and bonded over a meal. "That was absolutely insane. When you're telling it, I can't believe that happened," Cooper said, adding he felt nervous singing for her.
