The country music superstar hopped up onstage to serenade her man with “Happy Birthday” near the end of his concert set at the Darien Lake Amphitheater in Buffalo, New York, on July 16, noting that it was “the last show of his 20s.”

One fan, who got close enough to see the superstar’s serenade in action, recorded video of the performance, and posted a clip to Instagram.

As you can see in the video above, Miranda, who dons a pair of cowgirl boots, fishnets and daisy dukes, belts out the famous song with so much passion. She keeps her eyes affectionately glued on the birthday boy during most of the arrangement, but makes sure to take a moment to let the crowd sing along. Meanwhile, Anderson stands in the background looking oh so flattered by his blonde beauty’s gesture.

After the song, the couple hugs, and Anderson adorably gives Miranda an affectionate booty pat.

For the most part, Miranda and Anderson have kept their relationship private since they began dating each other in 2015. Even though they’ve given fans only small glimpses of their budding romance, they’ve celebrated plenty of holidays and special occasions together. It’s so sweet that fans got to enjoy this one!

Anderson is currently on the road playing select dates for Chris Stapleton’s “All-American Road Show Tour.” Brent Cobb, Brothers Osborne, Lucie Silvas and Margo Price are also featured artists on select dates for the tour.

Happy birthday, Anderson!
