The No Doubt singer posted the cutest clip of the lovebirds on Twitter Monday night while wishing a Merry Christmas to all of her many followers on social media.
The video shows Shelton kissing Stefani's cheek multiple times as the mother of three breaks out into a smile from ear-to-ear. And between the adorably matching outfits, the smooch itself and how happy they both look, it's safe to say that these two are going to have a wonderful upcoming holiday together.
In fact, a source told E! News earlier today that The Voice co-stars "spending a lot of time together" and "getting more serious."
