The 62-year-old country music icon joined Olivia on stage to perform If It Makes You Happy, from Sheryl's 1996 self-titled album.

It's not the first time the pair have joined forces, as the two sang the same hit at Sheryl's induction into the Rock and Roll Hall of Fame last November.

Olivia praised the All I Wanna Do artist as she introduced her to the crowd at Saturday's show, calling her "one of the most talented, most wonderful, kindest human beings" she had ever met.

But Sheryl wasn't the only music legend the vampire artist met in Nashville, as she also shared some photo booth pictures with former White Stripes frontman Jack White.
