The NBC special, "A Michael Bublé Christmas," will air December 6. Stories from New York suggest Kellie Pickler could be part of the show. Pickler tweeted from New York recently and a makeup artist said she saw Pickler on stage with Bublé.
Here's a tweet we picked up.
“Back stage with Michael Bublé and Kelly Pickler! They’re singing the cutest duet together for Michael’s Christmas show!,” Belinda Moss tweeted.
The taping for the NBC special was November 4 in Brooklyn.
Bublé recently released an album of holiday standards. The CD includes a duet of "White Christmas" with Shania Twain among the 15 songs in the project.
