Nicole Scherzinger: I'm not always fierce

Nicole Scherzinger is a "goofball" when she's not being "fierce".

The former Pussycat Dolls singer fears she is misunderstood. Nicole believes people think she's a strong and sexy female 24/7, when in reality she's just an ordinary girl.

"I think it's natural that people would have misconceptions about me - they've seen me in the [Pussycat] Dolls and in my music videos, when I'm this sexy, fierce girl. And there is a side of me like that - I've got my Sasha Fierce [Beyoncé Knowles' feisty alter ego] in me. I've always had that," Nicole told British magazine more! "But then everyday I'm just a normal girl. I'm a goofball. I have a sense of humour and people don't always get to see that."

The 34-year-old admits there is some truth to people's misconceptions about her. She judged last year's American X Factor and is now on the panel of the British show. She cracks the whip when it comes to her contestants as she is a workaholic.

"I do work so hard, so that's where the whole 'crazy b***h' thing came from," she revealed. "But I want to bring energy and fun to the panel."
