London, May 27 (ANI): Tulisa Contostavlos has confessed that she may not sing on the X Factor this year after her unsuccessful Britain's Got Talent performance.

The 'N-Dubz' star performed her No.1 single 'Young' on the talent show earlier this month and was criticized for her half-hearted dancing and dodgy outfit.

Asked if she would sing on this year's X Factor, she said it depended upon the timing of her solo albums.

Obviously I'll have more singles out this year so it just depends if the timing of the single is when the show is on. It's a possibility but I've got no idea yet when my next one will be out, the Sun quoted her as saying.

Tulisa also added that she doesn't plan to change her mentoring style, which saw her find success with show winners Little Mix last year.

I'm definitely not going to try to do anything differently - but obviously I've matured in the past year, she said.

I managed to have a laugh last year but I just think I am going to be less worried about what people think, she added. (ANI)
