Pregnant Mariah Carey gets into the Christmas spirit by performing at the Disney Christmas Parade. The 40-year old singer began signing, All I Want For Christmas Is You, while sitting in a horse drawn carriage and then went on stage. Disney characters, Mickey and Minnie Mouse danced alongside the songstress when she donned a Mrs. Claus outfit and performed Oh Santa. Given the fact the her child is due in the spring, Mariah is really packing on the pounds, I for one still believe there is more than one bun in the oven!
