Happy to share the spotlight with a young couple in love, Justin Timberlake helped a concertgoer propose on Sunday (December 15).

At the Louisville, Kentucky stop on his tour, the "Mirrors" singer singled out Josh from the crowd, who had his girlfriend Kim with him.

Cluing Kim in on what's going on, JT told the audience, "Josh called me earlier, he's got something he wants to say."

Stepping offstage to let them have their moment, the happy couple got engaged right on stage to the screams of the packed arena. Check it out in the video below.
