Lady Gaga feels like "a loser kid"

Lady Gaga says she feels like "a loser kid in high school"

The star broke down in tears during an interview for a new HBO documentary about her US Monster Ball tour - you can see a sneak preview clip below.

Gaga says: 'I still sometimes feel like a loser kid in high school and I just have to pick myself up and tell myself that I'm a superstar every morning so that I can get through this day and be for my fans what they need for me to be.

'But sometimes I still feel like people are trying to destroy me. I cannot be destroyed, I will not be destroyed and you will never destroy the kingdom that is my fans. I'm fighting for every kid that's like me, that felt like I felt and feels like I still feel.

"It hurts when I know how much authenticity and how much genuine blood is in my spirit and how much I feel like people don't know that... 'cos they see wigs and lipstick and they shut down, 'cos they don't understand.

"I just wanna be a queen for them and sometimes I don't feel like one. It's not about being a winner for me any more. It's about being a winner for all of them.'

The video was filmed backstage at New York's Madison Square Garden.

Lady Gaga Presents The Monster Ball Tour: At Madison Square Garden is due to air on HBO in the US on May 7.
