"Nicole Scherzinger has revealed that she once struggled with bulimia. The former Pussycat Doll opened up about her body issues in an interview for VH1&amp;#039;s Behind The Music, which is due to air this weekend.  &amp;quot;I just hated myself,&amp;quot; she said of her time in the all-girl group. &amp;quot;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.&amp;quot; The 34-year-old star admitted that instead of turning to drink or drugs, she got into the habit of making herself sick after performances. &amp;quot;I guess it was like my addiction, right?&amp;quot; she explained. &amp;quot;I never did drugs, but kinda doing things to myself was my addiction.  &amp;quot;It&amp;#039;s like when I got off stage, I was on this high, and I&amp;#039;d come back to my room and I&amp;#039;d be alone, so I would just do things,&amp;quot; she added. &amp;quot;My bulimia was my addiction. Hurting myself was my addiction.&amp;quot;  Scherzinger - who left the Pussycat Dolls in 2010 to launch a solo career - also revealed that she hid her illness from her bandmates. &amp;quot;I did it every day for, like, years,&amp;quot; she said. &amp;quot;Every time I had a second to be alone, I was doing something to myself.  &amp;quot;You get, like, blisters on your hands or scars on your hands, and I&amp;#039;d try to hide those. I think the girls could tell.&amp;quot; During the VH1 special, the X Factor judge also confessed that she sang &amp;quot;95%&amp;quot; of the bands vocals. &amp;quot;I love those girls, they&amp;#039;re like my sisters,&amp;quot; she said. &amp;quot;But people don&amp;#039;t even know the story. They have no idea.&amp;quot; She added: &amp;quot;I was in the centre because I was singing. I was the [only] one singing.&amp;quot; Nicole Scherzinger&amp;#039;s episode of Behind The Music airs October 7 on VH1.
