Justin Timberlake shows aren't just concerts. They are romantic events...at times. The singer stopped his show in Louisville, Ky., on Sunday, Dec. 15, so that a fan in the crowd could pop the question. Can we get an "Awww?!"

Josh, aka the future groom, contacted JT's camp last month to see if they could help him arrange a proposal to his girlfriend, Kim, during the concert.

JT, himself a hubby to actress Jessica Biel, is a romantic at heart and agreed.

After he delivered his rendition of 'That Girl,' he addressed Josh and Kim in the crowd and invited them onstage. "Josh called me earlier. He's got something he wants to tell you," the singer told Kim.

The twosome were in the middle of the stage, while JT fell in line, allowing them to take the spotlight and enjoy the huge moment in front of thousands.

Josh got down on one knee, presented the ring and popped the question. They kissed and hugged, and JT applauded.

Congrats to Josh and Kim -- since it's pretty obvious she accepted!
