After spontaneously handing out 750 gift cards to Walmart shoppers earlier this week, Beyonce has once again proven that she has a heart that's just as big as her larger-than-life image.

During her concert in Las Vegas on her Mrs. Carter Show world tour earlier this month, the 32-year-old mega star made a dying little girl's wish come. Thanks to the Make-a-Wish Foundation, Taylon, a young girl who was diagnosed with an inoperable brain tumor, got a chance to dance and sing with her idol on Dec. 6, reports NBC's Today.

Taylon's experience at the concert was and documented and uploaded to Beyonce's YouTube page on Christmas Eve.

"They found an inoperable tumor on her brain, and her dying wish was to dance with Beyoncé," says Ivy McGregor of Philanthropy Program Partnerships in the video.

In the clip, Taylon is seen frequently seen bursting into tears and visibly bouncing with excitement during the show. In another scene, Beyoncé flies over to Taylon's seat in a harness to hug her young fan. They then share a little duet singing "Love on Top" before Beyoncé sings her Destiny's Child anthem "Survivor" while dancing with Taylon.

"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.'"

At the end of the video, Taylon wipes away her tears as her mother leans in to comfort her emotional daughter.

Taylon, whose last name and age have not been released, is suffering from inoperable brain cancer.
