Let the holiday celebration begin! With her new album Merry Christmas II You in stores now, Mariah Carey gets in the X-mas spirit in the Ethan Lader-directed video for “Oh Santa!” Styled like a ’50s variety TV show performance, the festive clip sees the pregnant songbird spreading cheer in a sexy Santa outfit while backed by a band, dapper dancers, cheerleaders, gospel singers, and school boys. Even Santa himself can’t resist popping in to pay a visit. Watch Mimi’s Christmas spectacular below.
