I will not believe anything until it comes from Simon's mouth himself

I know, right?

It's true though, Demi is an amazing singer!

This is such a mistake. Britney will be bad enough but Demi... Oh god.

one of the best vocalists: demi lovato on one of my fave shows, X Factor!

couldn't have chosen anyone better.

hopefully it's true.

Britney hasn't been herself since the Circus era so why are you trying to put numbers into anything? I'm talking personality, something they need ya know..to do their job...JUDGE.

Yup.

and your avi is flawless Aubrey

I will have the greatest meltdown ever if she not.

Just saying, this goes both ways.
If we can't predict how Britney will be, then we can't predict how Demi will be either

Anyway, if this is true, I'm really eager to find out how she'll do
I think she'll be good but she obviously has to prove herself

Demi Lovato must be a joke? She's not even as commercial as Selena so what are they thinking? She's not a worldwide icon and she's not even a scratch on Britney Spears legacy...It's just a complete joke, how can she mentor someone to become a global success when she's yet to show that herself? #Next.

hmmmm this should be interesting i wonder if Demi really is going to be on the show but would E lie??

Let's be real here. Who's album is still stuck 300,000 US sales and hasn't even broken gold even though she spent weeks promoting it everywhere? Don't talk about careers when 14 years into her career Britney can sit at home sipping Starbucks & STILL have her "flop" album outsell twice these new girls'. You really tried it though. Back to Radio Disney for her.

Why is everyone so against Demi....Think about it Demi is a mini- Xtina shady an all. You know everyone gonna watch for Britney but I truly believe Demi will steal the show.

Can you guys just stop like seriously??? The shade is beyond pathetic from both of you

You directly mentioned Britney's career as being "lifeless", i'm just showing you the hard facts sis. You should be smarter about what say then.

And like I said, you haven't watched the show like the rest of us, so how about you sit and wait for it to air?

but why are you taking it that serious sis damn

I like Demi and support her but, this isn't a good decision. She is way too young and inexperienced to be judging and mentoring anyone. And should I also say she has shown she doesn't have the best judgement either?...

Right? Demi's just there to have someone to seat next to L.A.

This is fun!

Same.
