Stefani shared several adorable photos with her man while in Las Vegas for the Billboard Music Awards on Sunday night.
In the first photo, Stefani wrapped her arm around Shelton’s shoulder as they smiled for a close-up shot.
Another shot showed Stefani laughing while Shelton kept her close.
The couple gave a passionate performance of their song “Go Ahead and Break My Heart” at the awards show, locking eyes with each other throughout the entire duet before embracing at the end.
“I’m excited because this is a song Gwen and I feel so close to for obvious reasons,” Shelton, 39, told PEOPLE after the pair performed the song live on The Voice. “It’s as brutally honest and straightforward as you can be in a love song.”

Shelton and Stefani, 46, – who have been dating since late last year – co-wrote the song about getting over their trust issues following both of their divorces earlier in 2015.
Shelton explains, “We were getting over it, but we wrote this song about it, and it’s perfect.”
