Good for her... guess that's one of the reasons she didn't want to talk about Idol.

Omg yes

Hope RAT doesnt perform with her!!!

Can NOT wait... Will Mariah give ha a standing o?

Oh **** YAS

Depends on the quality of the performance. Wouldn't count on it.

Everyone's eyes will be on Mariah during and after that performance, I hope Mariah will swallow her pride and give her a standing O to shut this feud down !

No she won't handle the slayage.

I can't wait for the gifs

This will be her 3rd year in a row performing on the show! (OTF, DA, and now LIU). Looking forward to it

Also, in b4 the "I don't know her" gif

What was going on in that GIF?!

That would be the best tbh.

Exciting!
I hope J.Lo & Mariah pose for a picture together and finally lay all the rumors to rest.

First GMA
