Los Angeles: Singer Nicole Scherzinger says she might leave the US version of the 'The X Factor (US)' next year.

The former lead singer of the Pussycat Dolls said that she is going to focus more on her music because she could not devote much time due to her tight schedule as a judge on the singing competition, Ace Showbiz reported.

"Next year for me, it`s about my music. I am an artist first, not a judge. The show been so time consuming. I work with these contestants six days a week. So I delayed the album, but I was able to perform one of my new singles last week," she said.

The brunette beauty said although the show is quite a learning lesson for her.

"This has been quite a learning experience, quite a journey for me. I didn`t expect to have been so emotional through the whole elimination process. I wanted to just mentor and empower artists," she added.
