Rihanna just turned Mariah Carey’s Christmas concert into a fashion moment! She showed up in a little black dress with a sheer lace panel, a fur jacket, and gold bling—total showstopper vibes. Not only did she slay the look, but she also hung out with Mariah backstage, and even Mariah’s son said RiRi was the sweetest. Can we talk about this iconic duo?! #Beauty #Rihanna #MariahCarey
