That brings us to the current version of A Star Is Born, starring Cooper and Lady Gaga as Jackson Maine and Ally. Jack, an alcoholic singer who is on the opposite side of his arc to fame, meets Ally in a drag bar. They spend the whole night together before Jack takes her back home to her dad. But unable to forget about her, he sends his driver to bring her to his show, and it's there that he brings her on stage for the first time.
The two fall madly in love and Ally's career takes off, though the two still deeply struggle with Jack's drinking problem. When Jack ruins Ally's acceptance speech for her Grammy Award for best new artist, they realise that he truly needs help.
He goes to rehab for months, and during that time, Ally finds a love song he'd started to write for her. When Jack returns home from rehab, Ally tells her manager, Rez (Rafi Gavron), that she needs to either bring Jack on her European tour with her or she wasn't going to go at all. And it's while Ally isn't home that Rez shows up at their front door and tells Jack how much he's ruining Ally's life and career.
Ally tells Jack she's canceling her European tour so she can stay home with him and work on her second album, but he knows otherwise and can't move past what Rez told him about holding her back. After she leaves the house for her show, he hangs himself in their garage.
In the end, at a memorial service for Jack, she performs the song he wrote for her that she found while he was in rehab, and she introduces herself to the audience as Ally Maine for the first time.
