We never had doubts that Taylor Swift is a stand-up kinda gal, but this just solydifies her induction into the 'Do-Gooder Hall of Fame'!  It took a whole year, but Kevin McGuire, the Somerdale, New Jersey teen with cancer who asked Taylor to prom via YouTube, finally got to go on a date with her!

McGuire, originally invited Swift to his Sterling High School prom last year, but her busy touring schedule left her unable to attend.

So she offered him the chance to accompany her to the 2012 Academy of Country Music Awards but the teen fell ill due to his ongoing battle with leukemia!
