Listen to Blake Shelton on iHeartRadio

(Yahoo!) - Blake Shelton is hosted his first Christmas special, Blake Shelton's Not-So-Family Christmas, Monday night on NBC.

When asked to choose his favorite thing about the show, Shelton had a non-smart-aleck answer: His mom, Dorothy Shackleford, who also joined the cast and even sings a number live with her son.

"I have to say the biggest moment was having Mom come out there and sing with me," Shelton smiled backstage after the show's taping. "She's not a singer--I mean, she can sing, but she's not a singer. And then to bring her out here on national television and have her sing with me...and she did it like a pro, like she does it every night," he enthused.

"I wish some shows I see on TV, people sing as good as my mom," the famous coach from The Voiceadded. "I thought she nailed it."

Shackleford--who made her very first stage debut at the show's taping--actually wrote and recorded the song, "Time for Me to Come Home," with Shelton for his Cheers, It's Christmas album, which was released in early October. She noted after the show that her performance felt "nerve-wracking," but that she's actually been a prolific songwriter over the years: "I've wrote tons of songs, I just haven't had any recorded."
