The 46-year-old singer will be performing "Go Ahead and Break My Heart" with her boyfriend, Blake Shelton, on Sunday at the T-Mobile Arena in Las Vegas. Ahead of the awards show, Stefani gave her fans a sneak peek look at how the two are gearing up for the star-studded night.
The blond beauty kept her rehearsal look casual, simply donning a black turtleneck and pulling her hair back into a high ponytail. While Shelton was rehearsing his verses from the duet, Stefani kept herself busy by snapping pics with the crew inside the venue -- which just so happened to have the seating cards in the background.
Stefani will be sitting just two few seats away from fellow rocker, P!nk.
The "Misery" singer couldn't seem to take her eyes off her boyfriend during rehearsals, snapping multiple pics of him in action.
Once rehearsals wrapped, the pair got into a car and drove to a Mexican restaurant for dinner, where they celebrated Shelton's latest album, If I'm Honest, going No. 1 on the iTunes charts with margaritas and "melted cheese and chips."
