Beyoncé and Mariah Carey celebrated the season by performing holiday songs (well, kinda). Beyoncé performed her rendition of “Ave Maria” on NBC’s “Christmas in Rockefeller Center,” while Mariah was on CBS singing “Christmas (Baby Please Come Home)” on “The Grammy Nominations Concert Live!! — Countdown to Music’s Biggest Night” (video below).

Mariah only received one GRAMMY nomination for the gospel song “I Understand” and it wasn’t even on her own album. What’s up with that? We’re surprised she even agreed to perform.
