Need a good cry? Over a week after the surprise, Internet-breaking release of her titular fifth album, Beyonce wrapped up her epic Mrs. Carter Show world tour in Brooklyn just before Christmas. But it was during a Las Vegas show earlier this month that the superstar, 32, helped create an unforgettable moment for one terminally ill young girl and her loved ones.

As coordinated by the Make-a-Wish Foundation, young Taylon attended Beyonce's show -- with the Grammy winner singing and dancing with her.

A heartbreaking video on YouTube documents the special moment. "They found an inoperable tumor on her brain, and her dying wish was to dance with Beyoncé," Ivy McGregor of Philanthropy Program Partnerships explains. With Beyonce arriving right by Taylon's seat, the pair sang Destiny's Child's "Survivor" together as well as "Love on Top."

"Here's a little girl literally fighting for her life," McGregor explains. "'Tomorrow's not promised, next week's not promised, but right now I'm here,' and her thought that will forever stay with me is, 'Since I'm here, I might as well live.'"
