Justin Timberlake Becomes Matchmaker In Concert

It's Justin Timberlake—secret matchmaker.

At first it looked as if the singer was just chatting with two random fans, at a concert, but then he asked the couple up on stage. It became apparent that Timberlake and the male fan were up to something.

Joshua Clemons suddenly got down on one knee and proposed to his stunned girlfriend Kim Martin at Timberlake’s concert in Louisville, Kentucky.

Timberlake posted video of the romantic moment on his website.

It turns out, this love story has a somewhat bitter twist. Clemons' ex-wife also went online to post some edgy remarks.

INSIDE EDITION’s Megan Alexander spoke to Clemons and Martin via Skype.

Alexander asked, "Josh, how do you feel about your ex-wife having to see this video that has now gone viral?"

Clemons said, "She told me, 'Good luck,' on the way to the concert. She knew about it and was happy for us. I am the type of person that is not going to let negativity get me down."
