Justin Timberlake proves to the world why we gals love him so much. He unites us all in an "aww" moment as he collaborated with an attendee of his 20/20 Experience concert to propose to his girlfriend.

During his Louisville, Kentucky concert Justin had a big surprise for a special gal in the audience. It turns out that the "Mirrors" star had been contacted (how do you contact a superstar?) by Kentucky resident Josh back in November. He asked Justin to help him propose to his girlfriend during his concert, and JT, being the sweetie that he is, immediately agreed.

During a rendition of his song "That Girl" Justin all of a sudden stopped the concert. He invited Josh and Kim on stage with him, as if this was just another part of the concert. Kim had been enjoying her front row view of the concert and had no idea what was going on. Justin put his acting skills to use as he asked Josh his name and randomly spoke to him.

"Guys, say hello to Josh! Who do you have with you tonight? As he introduced Kim to the audience he admitted to knowing what was going on saying: "Josh called me earlier, he has something to tell you." He pushed Josh forward and he nervously got on one knee and asked Kim to marry him. Lucky for Josh, she didn't hesitate to say yes. The crowd screamed as Kim and Josh kissed in the middle of the stage.

Aw, Justin, why are you so great? The "Suit and Tie" star is known for his "well-doings" buying pizza for a crowd who waited in freezing temperatures outside of his Saturday Night Live performance rehearsals. He also accepted a female marine's YouTube invitation to the annual Marine Corps Ball in 2011. JT will continue his 20/20 Experience world tour in the US until March next year as he performs at New York's Madison Square Garden and LA's Forum venue. The tour comes to the U.K. on Mar. 30 2014.
