Just weeks after taking time out to sing a heartwarming duet with a 13-year-old blind fan during a concert in Perth, Australia, Beyoncé is once again bringing us to tears.

On Christmas Eve, a video was posted on the singer's YouTube page of the pop star making a young girl's wish come true.

In the clip, we meet Taylon as she attends a Beyoncé show earlier this month in Las Vegas, thanks to the efforts of the Make-A-Wish Foundation.

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

Sure enough, that's exactly what happened when Queen B made her way over to Taylon, crouched down and gave her a hug as she sat in her wheelchair.

Soon, a crying Taylon was on her feet dancing as she and Beyoncé sang the Destiny's Child hit "Survivor" together.

"Here's a little girl literally fighting for her life," says McGregor. "'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.'"
