Nicole Scherzinger has revealed more about her struggle with an eating disorder, saying she felt too ashamed to even tell her mum.
The X Factor judge admitted last year that she used to suffer from bulimia, but had never told her family.
In an exclusive interview with OK! magazine, she has talked again about how the condition affected her.
Nicole, 34, said: "I was too ashamed to tell anybody."
She also said that her own mother only found out about her bulimia when she opened up about it in a previous interview for VH1 Behind The Music last October.
The former Pussycat Doll said that her mum was extremely upset and 'cried for a long time'.
She said: "If she'd known at the time it would've broken her heart."
In the documentary Nicole, whose boyfriend is Lewis Hamilton, talked about dealing with the eating disorder in her teens and during her time with the Pussycat Dolls.
She said: "My bulimia was my addiction, hurting myself was my addiction.
"I've never spoken about it. It's embarrassing... I did it every day for, like, years... I hated myself. I really was so disgusted with myself... I felt so alone; I was in a group and I never felt so alone in my life."
