Are they preparing for another cat fight??
We think we know who'll win.
Mariah Carey did a perfect job of upstaging Nicki Minaj on the set of filming American Idol in Los Angeles on Wednesday.
She wore a slinky figure-hugging red dress like the FABulous diva that she is, while Nicki kept it on the boring side with black pants, top and jacket.
The two ladies were then later joined by their fellow judges Randy Jackson and Keith Urban before getting their makeup touched up.
If Mariah looks just as incredible as she does (above) then we're in for an amazing season of AI! The new season premieres January 16 on Fox.
