But lead singer Scherzinger admits she'd never seen anything like them growing up in Louisville, Kentucky - and she felt uncomfortable baring so much flesh onstage.

She tells Britain's Cosmopolitan magazine, "Growing up, I was very conservative in my wardrobe, so when I first joined the Pussycat Dolls, the biggest challenge was wearing those cabaret costumes.

"I didn't feel comfortable showing my body so much, showing my legs and butt, chest and midriff. I wasn't used to it so I had to really grow as a woman and learn to accept myself and my body, find that inner confidence and strength and love myself for who I was."
