Jon Pardi is getting married! The "Heartache Medication" singer proposed to his girlfriend, Summer Duncan, during his headlining set at Nashville's legendary Ryman Auditorium on Wednesday night (Oct. 2).

Pardi's friend Dierks Bentley was on hand for the special moment, since he was watching Pardi's show from the side of the stage. He turned to Instagram to post a picture of Pardi's proposal, which earned a "Yes" from Duncan and an ovation from the crowd in Music City.

"My man! @jonpardipics crushing the @theryman stage and crushing life... so proud of you pal. Killer show with my all time fav encore. Congrats to you and @summerfawn_duncan," he writes.

Entertainment Tonight reports that Pardi told his audience that the Ryman was one of the first places that he and Duncan ever went on a date. Wednesday night's show marked the second of two back-to-back nights he headlined at the iconic venue. The 34-year-old country singer and Duncan have been dating for about two years.

Pardi just released his third solo album, Heartache Medication, on Sept. 27, and he tells Taste of Country Nights that Duncan was instrumental in convincing him to cut one of the album's focus tracks, a song titled "Old Hat." He gushed about Duncan's impact on his life in speaking to Entertainment Tonight recently, saying, "Life with Summer is awesome… When it comes to singing about losing her, it’s a big no for me. I definitely want to make her happy."

"I’ve had my fair share of crazy girlfriends," he added. "So it’s nice to be in a totally sustainable relationship... I mean, I still do dumb [things], I’m a guy, but for the most part, I’ve got to pat myself on the back. I’ve been a good boyfriend and it’s nice to really work to make somebody feel loved and feel happy... she’s worth it."
