“Extra’s” AJ Calloway sat down for an exclusive interview with Mariah Carey at Dylan’s Candy Bar, where she treated children from the Fresh Air Fund to gingerbread houses and a meet and greet with Santa. Carey has a lot to celebrate this year, kicking off her “12 Days of Christmas" on NBC and selling an unprecedented 14 million copies of her "Merry Christmas" album, but she is also looking forward to spending time with twins Moroccan and Monroe and husband Nick Cannon in Aspen this holiday season.
