john legend might be right about britney's voice, but he misses the point that it doesn't really matter. britney is someone who knows showbusiness inside out. by john's standard, simon cowell shouldn't judge, because he can't sing!

He's right about Britney but he's wrong about Demi. Demi Lovato can actually sing. What people need to realize is that you don't have to be a great singer in order to know if someone else can sing. There are plenty of us 'regular' people who can't sing at all but who still point out which singers we think are talented and which ones we don't. My only problem with Britney being on this show is that I'm afraid she'll candy-coat things and be afraid to give honest criticism. When Christina Aguilera (on The Voice) gave criticism that was direct and honest to a contestant that people liked, everyone basically called her a bitch and accused her of being bitter. That's how immature people are. I'm afraid that Demi might be too nice too.

I agree that britney is not that great of a singer but she is one hell of a performer and has made hit after hit. thats what the x factor is to me.

Even if he is right, he doesn't have the right to bash them, whether in public or in private.

He wasn't talking about Demi, he was talking about Britney, but did want to say her name. He's right though everyone knows her voice is mostly a machine and production, we know this about Britney and those that continue to buy her music know this too, it wasn't like he wasn't telling the truth
