Bradley Cooper felt 'comfortable' singing with Lady Gaga

Actor Bradley Cooper, who is all set to show his singer side in the upcoming movie 'A Star is Born,' has revealed that he felt "comfortable" singing with Lady Gaga in the movie.

According to Entertainment Weekly, the 42-year-old actor revealed that he was not fazed about belting out the ballads with the 31-year-old singer.

Cooper said, "She made me feel comfortable."

The 'Burnt' star also shared that he never felt he was "nuts" for taking to the stage alongside the 'Joanne' singer for certain scenes in the film.

"I never had to deal with the reality of asking myself, 'Are you nuts, putting yourself on stage with Lady Gaga?" noted Gaga.

But Bradley is not the only star who enjoyed working on the project, as Gaga loved working with the ''dream team''.

Alongside a post of her on the set, which was previously shared on her Instagram account, she wrote, "That's a wrap on #AStarIsBorn Flowers for my directors and producers. absolutely a dream team."

In June, the 'American Sniper' actor appeared on the stage ahead of Kristofferson's set at Glastonbury Festival and performed for the crowd and cameras, with his guitar volume turned off to the audience.

Cooper is directing and starring in the film alongside Lady Gaga. He and Gaga filmed similar scenes at Coachella in April.

Cooper's version, which is scheduled to be released in 2018, is the fourth version of the film, following the 1937 original with Janet Gaynor and Fredric March and 1954's version starring Judy Garland and James Mason.
