Nicole Scherzinger at the Cosmopolitan Ultimate Women of the Year Awards

Nicole Scherzinger believes in "female empowerment".

The singer says years of being in The Pussycat Dolls and facing criticism from others has given her a strong sense of girl power and she wants to take a stand against putting other women down, and has started her feminist crusade with her fellow 'X Factor' UK judge Tulisa.

Speaking at the Cosmopolitan Ultimate Women of the Year Awards 2012 with VO5 on Tuesday night (30.10.12), Nicole told BANG Showbiz: "I have my music, my message, I was in a girl group. It's always been about female empowerment. It wouldn't be right if I turned my back on another female on the same [judging] panel. It just wouldn't be right.

"We all have insecurities as girls, if we turn our backs it's just from our own insecurities. So it's up to us to be open and loving towards each other, to bring that other side out in each other."

The 34-year-old singer stunned in a backless white dress as she accepted her Ultimate Fun Fearless Female award at the glamorous ceremony at London's Victoria and Albert Hall.

Tulisa battled it out in the style stakes with Nicole and was granted the Ultimate TV Personality, joking as she accepted her gong: "For the first time in many nights I'm actually sober! Giving myself applause for that."

Another well-deserved winner was Kelly Osbourne, who picked up the Ultimate Style Award and proudly announced: "I used to look like s**t. I never thought I'd get a style award. Cosmo putting me on their cover a couple of years ago did wonders for my self-esteem."

A galaxy of stars attended the glitzy event, including One Direction, Girls Aloud singer Kimberley Walsh, Alexandra Burke and Professor Green.
