(Cover) - EN Showbiz - Nicole Scherzinger thinks sex appeal is innate.

The Pussycat Dolls singer believes sass cannot be manufactured, but has to come from inside. Nicole prides herself on being confident with her body and recently appeared as a guest judge on British television contest The X Factor, where she wore a series of figure-hugging frocks and could be seen jiving along to contestants performances.

I think being sexy comes from within, she told the British edition of OK! magazine. You have to feel it.

Nicole revealed she suffers from body hang-ups like all women, and isnt always happy with her looks. She explained she feels her most comfortable on a platform commanding a crowd of fans.

I feel the sexiest when Im on stage with the Dolls because I feel like nothing can touch me, she said. Although I want to touch everybody in some way.

The 32-year-old is dating 25-year-old Formula One champion Lewis Hamilton. They are very happy together, and Nicole feels blessed that her life has worked out so well. She wants to encourage other people to follow their dreams as she did, saying its important to give your ambitions your all.

Just go after it! she said. Dont let anyone or anything get in the way. Knock on every door of opportunity. Believe in yourself. (C) Cover Media
