Stefani looked like perfectly wrapped package during the performance, donning a sexy red ensemble, while Shelton wore his usual jacket and jeans. While the two kept the PDA to a minimum on stage, they clearly couldn't take their eyes off each other!
"Yay!! It was incredible to write with @BlakeShelton & share the stage for a song that is so joyful & Christmas-y! #YouMakeItFeelLikeChristmas #LuckyGirl ? ✨," Stefani tweeted after their performance.
"It's interesting because you really don't realize what love can do and how dangerous it can be, and how it can break you...and save you at the same time. I feel like it's very Christmassy, because Christmas is about being saved, really," she recently told ET of the performance. "I think that when you're a mom, all you really care about [is your kids'] happiness, right? Nothing really else really matters, and I think that's probably what she still feels."
