AceShowbiz - Ahead of "A Star Is Born" premiere in the United States, Lady GaGa has kept fans hyped by releasing her collaboration with co-star Bradley Cooper titled "Shallow" on Thursday, September 27. The release of the song was accompanied with a music video which was premiered on the same day.

The visuals sees Cooper's Jackson Maine performing the song on stage as GaGa's Ally watches from the crowd. Watching her mentor and love interest perform, Ally gains the courage to join him onstage, though she looks reluctant at first.

But all of her worries fade out when she finally reaches the chorus, earning a loud cheer from the audience when she successfully hits the high notes. Maine is proud of her for braving herself to sing in front of a large audience, so he excitedly strums his guitar as Ally continues singing.

The music video also features scenes from the movie which show how Ally and Maine's relationship turns into romance as well as Maine's struggles with drinking.

"Shallow" was written by GaGa along with Mark Ronson, Andrew Wyatt and Anthony Rossomando. She co-produced the track with Benjamin Rice. Talking about the song during an interview with Zane Lowe of Beats 1, the "Poker Face" hitmaker said that "Shallow" occurred at such a "crucial moment" in the film. "It's two people talking to each other and talking about the need and the drive to dive in to the deep end and stay away from the shallow area," she said.

"A Star Is Born" follows the story of Jackson Maine who discovers -- and falls in love with -- struggling artist Ally. She has just about given up on her dream to make it big as a singer until Maine coaxes her into the spotlight. But as Ally's career takes off, the personal side of their relationship breaks down as Jack fights an ongoing battle with his own internal demons.

The movie will hit theaters across the nation on October 5, the same day the soundtrack album will be released.
