Nicole Scherzinger has revealed she struggled with bulimia and self-harm during her time in the Pussycat Dolls.

According to The Sun, The X Factor judge opened up about her past demons in the VH1 documentary Behind The Music.

And Nicole admitted that the eating disorder led to self-loathing, saying: "I just hated myself. I really was so disgusted with myself and so embarrassed.

"I felt so alone. I was in a group, and I never felt so alone in my life.

"I did it every day for, like, years. Every time I had a second to be alone, I was doing something to myself. You get, like, blisters on your hands or scars on your hands, and I'd try to hide those. I think the girls could tell."

The Try With Me singer went on to describe self-harming and bulimia as an "addiction".

She said: "I never did drugs, but kinda doing things to myself was my addiction. It's like when I got off stage, I was on this high, and I'd come back to my room and I'd be alone, so I would just do things. My bulimia was my addiction; hurting myself was my addiction."

Despite struggling with life in the pop spotlight, Nicole admitted she was too embarrassed to tell anyone about her problems.

Thankfully she won the battle thanks to music. She added: "The music is what saved me. It's the only thing that I can trust."
