mariahcareypic230.jpgMariah Carey, and her baby bump, plan to hit the stage for an ABC special called Mariah Carey: Merry Christmas to You.

For the holiday concert at the Orpheum Theater in Downtown LA, Mimi will be singing Christmas classics, and of course, new tracks from the album Merry Christmas II You.

We're also told that Nick Cannon's wifey, 41, will be granting special wishes to some lucky fans. Perhaps an autographed copy of Glitter?

The ABC special will air on December 13.
