Justin Timberlake has admitted he could never become a TV talent show judge.

The singer is currently in the throes of a music comeback as he builds up to the release of new album 'The 20/20 Experience'.

However, it seems signing up for a show such as the X Factor would be a step too far when it comes to promoting his brand.

Speaking to Capital FM, the 'Suit & Tie' star said that he is too nice to put people down and ruin their dreams. Timberlake said:

"I could never do that. I'd feel too bad, you know, to tell someone no. And it's obvious when someone's not good. But I just don't have the heart."

The former 'N Sync star meanwhile recently announced a summer stadium tour of North America alongside collaborator Jay-Z.
