Nicole Scherzinger says she is happy to be "wishy-washy".

The singer sits on the judging panel on the US version of The X Factor alongside Simon Cowell, Paula Abdul and L.A. Reid.

She's known for making comments which are sometimes hard to understand. Simon often teases her for that, but Nicole has vowed never to change.

"I don't care. I know what my comments are, and you know what? Sometimes I am wishy-washy. That's how my brain works naturally," she laughed.

Nicole is also proud of how driven she is, but that doesn't mean she never has any fun.

She enjoys relaxing with a movie and some cake on occasion and also parties with friends. When that happens people are often amazed as she is the "life of it", although the star rarely throws bashes at her own home.

"I don't allow a lot of people to come to my house," she told Look magazine. "I'm very private."
