Justin Timberlake won't be walking in his ex, Britney Spears' footsteps any time soon. He says that he will never take a job on a television talent show. He 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."Justin is releasing his new album, The 20/20 Experience on March 19.
