Justin Timberlake assists with marriage proposal at Kentucky concert Justin Timberlake, you romantic. The "Suit & Tie" crooner's role in one couple's marriage proposal made most other question-popping stories seem like amateur hour. After singing "That Girl," Timberlake abruptly paused his Louisville, Ky., concert on Sunday to innocuously address some fans in the pit. Or so it seemed. PHOTOS: Justin Timberlake's career in pictures "Josh and Kim, why don't ya'll make your way up here," Timberlake said, leading Josh Clemons and his girlfriend Kim Martin to the grand piano set up onstage. "This is Josh and Kim," Timberlake said. Josh called me earlier. He's got something he wants to tell you. Then he handed Clemons the mic and the fans lost it. Josh got down on one knee and, with a little help from Timberlake, asked his girlfriend to marry him. Based on the sound of the audience in the KFC Yum!

"And then this happened in Louisville... http://bit.ly/1hdn0Dp," he tweeted with a link to the video posted on YouTube. Seems like Mr. Jessica Biel is all about spreading the wedded bliss.
