Well, at least Mariah Carey
's latest celebrity showdown
isn't against her fellow "American Idol" judge
, Nicki Minaj
! The pop legend wore a floor-sweeping, black-and-white Valentino gown to a live Q&A session at the "Idol" Season 12 premiere screening in Westwood, Calif. on Jan. 9. Just a couple of months earlier, actress Jennifer Aniston
appeared in the very same Valentino design at the American Cinematheque Award Gala in Beverly Hills. While Mariah went glam with massive, bejeweled drop earrings, signature butterfly ring and a high ponytail, Jennifer let her tresses hang loose and opted for minimal bling.
