Lady Gaga’s high school bullies inspired her role as struggling artist Ally in ‘A Star Is Born’.

The ‘Pokerface’ hitmaker plays struggling artist Ally in the hit movie and admits being bullied in high school helped her understand how her character felt.

She said: “Well, what’s different between Ally and I is that when I decided I was going to go for it as a singer and songwriter, I just hit the ground running. I was dragging my keyboard around New York and I was pounding on doors. I really believed in myself. Ally is not this way. My character in this film, she doesn’t believe in herself at all. She’s very jaded by the music industry and she’s given up on herself. What I had to do was go back further into my childhood, into my high school years, when I was bullied and made fun of for having big dreams. That’s where I went. But I think I went further because I trusted Bradley [Cooper] so much – to be vulnerable, to be my authentic self.”

And the 32-year-old singer and actress loved working alongside Bradley Cooper.

She added to People magazine: “He’s such an incredible director, he’s such an incredible actor. The experience of him acting and directing and producing and writing music at the same time was completely fluid. I’m just so grateful to be here.”]

Meanwhile, Bradley and Lady Gaga think they put their careers at risk with ‘A Star is Born’.

He said: “There are certain projects where you can go, ‘It didn’t work out, but it’s OK’. And there are others where it’s like, ‘Actually, that wasn’t OK, and I took about five steps back.’ This was one of those. If it didn’t work, we both knew it was going to affect our careers.”
