'It's heartbreaking,' Lady Gaga on being judged in Hollywood for looks

Lady Gaga says she identifies with her character in "A Star is Born" because as a struggling musician she felt discriminated for not being the "prettiest girl" in the room.

Gaga plays a talented but shy singer in the reboot of the film, which is directed by Bradley Cooper.

Cooper also plays the role of a self-destructive musician in the film and helps Gaga's young singer find her voice.

Talking about her early years in the music, Gaga told Entertainment Weekly, "When I wrote my earliest hits, people were trying to take my songs and give them to other people. I was, like, clutching to them for dear life, thinking, 'I finally wrote a hit. I can't give it away'.

"I was not the prettiest girl in the room. I was a little weird, and I liked being weird. I didn't like to be sexual in a way that other pop stars or pop groups were. I was my own thing. It's heartbreaking because you feel like, 'Why am I not enough?'"
