Jason Mraz often sings about the beauty and happiness of love, but fans at his most recent concert got to witness true romance in the making.

The crooner's show at the Gexa Energy Pavilion in Dallas, TX on August 11 was the site of a marriage proposal from one fan to another, captured in a YouTube video.

While Mraz was singing "I'm Yours," he walked across the stage to another microphone stand only to discover his mic was missing. After some giggles from the audience, Mraz began to sing again, and ended the song with some relationship advice for the fans.

"Go ahead and turn to the person you came with and tell them 'I'm yours,'" Mraz sang to the crowd, just before he called out to Ryan Morris, who had Mraz's mic. Watch the video to see what happens next; the proposal starts at 4:35.

Mraz is the second performer to give someone's proposal rock-star status this summer. Madonna also helped a fan pop the question in July.

Correction: An earlier version of this story reported that Jason Mraz is currently engaged. According to E! Online, among other sources, the singer called off his engagement. This post also misidentified Ryan Morris as "Brian." We regret the error.
