Mariah Carey's Christmas Time

It's not officially the holiday season until you hear Mariah Carey belting our her classic, "All I Want for Christmas is You," which is why the diva is bringing her festive tour to Allstate Arena in late November. She's got two albums worth of original and traditional Christmas songs to draw from, so expect plenty of sleigh bells, glittering yuletide gowns and a few unexpected gifts from Carey's catalog of pop ballads.
