Taylon is an 11-year-old Queen B superfan who uses Beyonce's voice to help cope with her cancer battle.
"They found an inoperable tumor on her brain and her dying wish was to dance with Beyonce," a spokeswoman said in a video posted on YouTube on Tuesday.
During Beyonce's Las Vegas concert earlier this month, she made Taylon's wish come true after she stepped offstage and wrapped her arms around the young star.
Beyonce and Taylon sang and danced together in front of thousands of screaming fans. It was a beautiful moment that brought the young girl to tears.
