Things are definitely getting serious!

Gwen Stefani took to Twitter on Monday to share a video of her and her new beau, Blake Shelton, showing off a little PDA.

In the cute clip, "The Voice" coaches are dressed in matching camouflage outfits as Blake repeatedly kisses Stefani's cheek.

"Merry Christmas," she simply captioned the cute clip.

Gwen and Blake both traveled to Nashville over the weekend to celebrate singer RaeLynn's engagement party. Judging by their outfits, it looks like maybe they also did a little fishing together while down South.

The "Used To Love You" singer likewise opened up about her relationship with the "Sangria" singer while chatting with Ellen DeGeneres in November, admitting that their whirlwind romance has been "a lot of fun."

"It's like a whole new life, a whole new chapter," she explained. "It's been so great to be on 'The Voice' and to be around all that music."

Stefani went on to gush about her beau, revealing one very surprising confession. "I did not know this about him because I didn't even know who he was before I was on the show. Before I was on 'The Voice,' I never heard of him before. I didn't. I hadn't. I'm an O.C. girl. Like, what would I know?" she admitted. "But he knows every single '80s song. He literally is a musical jukebox. He knows everything about music it's crazy."
