We're all about the warm and fuzzies this morning. Well, it is Tuesday after all.

As legend would have it, Justin Timberlake - who appears to be morphing into Michael Buble, by way of Derren Brown - put a halt to one of his recent concerts so a fan could propose to his future wife onstage. No pressure to say 'yes', or anything.

The singer/actor was performing in Louisville, Kentucky  as part of his 20/20 Experience Tour, but stopped the show after singing That Girl so one Josh Clemons could propose to girlfriend Kim Martin.

Justin headed over to the side of the stage, where he asked Josh if he had a drink, and invited him and the unsuspecting Kim to introduce themselves. He then brought them onstage, telling Kim: "Josh called me earlier. He's got something he wants to tell you." Let's assume - at that point - Kim's heart almost fell out of her arse.

The singer then exited as Josh got down on one knee and made his proposal, which Kim obviously accepted, sending the 22,000-strong crowd wild with congratulatory cheers.

Justin then returned, bringing the happy couple some shots and leading fans in a toast.

He said: "This is for Josh and Kim. Louisville is for lovers, baby!"

So, for all those planning on springing a surprise proposal in such a manner, it's not easy to pull off... Josh said organising the extra-special proposal took him over 100 phonecalls and emails. He told the WDRB.com: "On Friday I finally caught [Justin's manager] on the phone and he said Justin had a big plan and wanted to know if I was ready to do it big. I said definitely."

Kim was amazed by the proposal, and said Justin was a true gentleman when she met him backstage after the concert: "He was just very involved in this. I was very surprised he took initiative to help him so much and the way he talked with us."

"Refreshing" is the word you're looking for, Kim. Refreshing. And he knows the power of good PR.
