She is a former member of Pussycat Dolls, judge of American X Factor and one of the most top pop singers worldwide. However, if you think that she doesn’t fell insecure, then you wouldn’t be more wrong.

Scherzinger opened up during her interview with British Cosmopolitan about her “dark time” in her life, battling the bulimia.

“I had such a great life on the outside, the Dolls were on top of the world, but I was miserable on the inside,” the 36-year-old told the magazine.

“It is such a horrible, paralyzing disease and it was such a dark time for me,” the singer said of her past struggle with bulimia, which she first told publicly in 2012. “I didn’t think anyone knew in my group or in my family because I hid it that well, I was so ashamed. I knew it wasn’t normal or healthy because I was hurting myself through this cycle of disordered eating.”

Scherzinger continue by saying that she didn’t face her problem until she physically passed out on a tour.

“I had started losing my voice, I couldn’t sing at shows, and then I remember my manager finding me passed out on the floor in Malta or in the south of France,” she recalled. “I thought, ‘I’m going to lose everything I love if I don’t love myself’ … I’m never letting that happen again; you only get one life”.

Carmit Bacher, a member of the Pussycat Dolls, claimed in 2013 that Nicole’s eating disorder, which was kept secret from the group, led to tensions that ultimately contributed to the end of the group.
