Justin Timberlake just made one girl's special day way more exciting! 

At Timberlake's the 20/20 Experience World Tour in Louisville on Sunday, the pop star helped one lucky fan, Josh, propose to his girlfriend, Kim.

Check out the super sweet moment above! 

Josh popped the question after the JT performed "That Girl" and Kim definitely seemed more than surprised when Justin brought her and her now-fiance to the stage.

We think it's awesome that Timberlake took a few moments out of his performance to make the night extra memorable for two fans -- of course, Kim said "yes"! 

What do you think of Josh's proposal? Tell toofab in the comment section below!
