BRUNO MARS has promised to make one teen fan's 2013 prom night extra special after she offered up a plea for him to be her date on YouTube.com.

Emily Torres from Michigan got to meet her hero on a recent Ellen DeGeneres Show after she opened up to Mars with a musical plea.

The Locked Out of Heaven singer told his fan he would not be able to attend prom night with her, but revealed he had arranged for Gucci designers to fit her for the perfect gown.

He said, "I'm gonna hook you up with a dress to make you look just as beautiful and amazing as you are and when I come to the city near you I got four tickets for you and your friends so you can see me. You're gonna be front row and you're gonna be my guest."

Mars announced his upcoming Moonlight Jungle world tour on the show and then offered to dance with Torres at an impromptu prom staged in the TV studio
