Love them or loathe them, celebrities have the ability to impact people around the world. A handful have used their fame to bring a smile to children suffering terminal illnesses through the Make-A-Wish foundation.
There wasn't a dry eye in the house when Beyoncé serenaded 12-year-old Taylon Davis, a young girl with an inoperable brain tumor whose last wish was to dance with her idol. Bey seated Taylon and her mom in a special section of her Las Vegas concert and sang "Love on Top" and "Survivor" with the brave little girl.
