Nicole Scherzinger to quit 'The X Factor'

The 34-year-old wants to leave the show on a happy note, reported Sun Online.

"I'm really glad I did the show. I don't know if I'll come back next year. End on a high, right? This year has changed my life. As an artist, it's put into perspective what I want, how to go about it," she said.

The singer shares the judge's panel with Gary Barlow, Louis Walsh and Tulisa Contostavlos.
