Ugh. The Demi screech, against Ariana's beautiful voice.

Though where's the pressed Demi stan who is always criticizing Ariana's vocals? I need to see his reaction. Preferably recorded the instant he reads this thread.

I don't want the queen near that attention *****.

Yes!!!! So excited for this! I've been hoping this would happen!

No, Demi should collaborate with people as experienced and respectable as her, but Ari can keep wishing, it's a good thing for a person to do.

Here for Ariana outshining Demi's vocals on the song

Maybe Selena should join them on the song

Here for this! Interested in what sound they're going to choose, Demi's Pop-Rock or Ari's RnB/Pop-kida-thing...

Ariana, Demi, Selena and Miley should do Lady Marmalade 3.0?

Not here for this. Demi will ruin the song with her over singing

Ariana is a huge talent. She is already becoming very respected.

you're acting as if Demi is way superior than Ariana

ariana is far too successful and talented to be colaborating with the likes of demi.

I love Ariana but lets be real. Ariana is only on her first single. It's too soon to say something like that

Ariana's vocals are amazing but too lighty and breathy, on the other hand Demi's vocals have to much emotion and power that it's impossible for me to describe, so it would be a really good mixture of breathy and powerful hight notes! Good thing about it both can sing high notes and LIVE unlike others! here for this

yesss I'd love this!
