Gwen Stefani & Blake Shelton 'Make It Feel Like Christmas' on 'The Voice' -- Watch Their Adorable Performance!

Gwen Stefani and Blake Shelton are getting into the holiday spirit!

The lovebirds teamed up for a special performance of their new duet, "You Make It Feel Like Christmas," on Monday's episode of The Voice, melting our hearts with their powerful vocals and undeniable chemistry.

Stefani, 48, opted for a festive ensemble, consisting of a sheer black dress with red-and-green flowers, over-the-knee boots and her signature red lip. Her beau, 41, sported a more casual look -- a black vest and tie over plaid shirt and dark wash jeans.

Around the stage, their dancers pranced around in '50s-inspired garb: the guys in leather jackets, skinny jeans and Converse, the ladies in plaid poodle skirts, ruffled socks and turtlenecks.

"I never thought I'd find a love like this," Stefani sang, adorably staring into Shelton's baby blues. "But I found forever in that very first kiss. I wanna thank you, baby. You make it feel like Christmas."
