Mariah Carey and Madonna Mariah Carey and Madonna

Oh, to be a fly on the wall backstage at Wednesday night's Grammys. Sources tell the New York Daily News that Mariah Carey "really wanted to open the show with her choir-backed rendition of 'We Belong Together,'" but Madonna waylaid those wishes by giving producers an ultimatum: I open, or I don't show up. Thus, Madge (performing with the animated group Gorillaz) landed the plum placing, supposedly infuriating Carey and adding further fuel to the divas' long-running feud. I'd suggest the gals kiss and make nice, but Madonna has been there, done that with Brit and Xtina.
