Actor Bradley Cooper finds a friend in singer-actor Lady Gaga
"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.
"The only reason I had the courage is that she made me feel so comfortable."
"I don't even know how I would sing because I'm singing through him. He was a complete character. That said, there was one song that I wrote, called 'Too far gone' that I had the idea for a verse and a bridge, so I'm going to go to the recording studio and finish it," he said.
Cooper is known for "He's Just Not That Into You", "The Hangover", "Silver Linings Playbook", "Aloha" and giving voice for Rocket in "Guardians of the Galaxy" and in the sequel "Guardians of the Galaxy Vol.2" -- which will air on Indian small screen this month on Star Movies as part of Marvel Mania.
His directorial "A Star is Born" will release in India on October 12. Warner Bros Pictures is bringing the film to India.
