Blake Shelton fans were treated to one heck of a surprise on Friday night!
It was business as usual for the 40-year-old country star during his St. Paul, Minnesota, concert -- until Gwen Stefani made a surprise appearance!
"Hi Minnesota Gx," Stefani captioned a shot of herself in Shelton's tour bus before heading onstage.

The duo couldn't have looked more stylish while jamming to their duet, "Go Ahead and Break My Heart."

And of course the "Misery" singer couldn't leave before performing one of her own hits -- and getting a huge bow-down from her beau.

This isn’t the first time the couple has made a surprise appearance at each other's shows.
In fact, Shelton surprised Stefani's fans during her Detroit, Michigan concert just last month -- and the two couldn't help but cuddle up on stage.
