During a recent stop on Post Malone’s F-1 Trillion tour, a fan in the crowd caught the country star’s attention. A little five-year-old Posty fan named Ava was wearing a t-shirt that read, “My Make-A-Wish Is To Meet You. F**k Cancer.” The young girl is battling a type of brain cancer called pilocytic astrocytoma, and it has caused her to lose her sight. When he noticed Ava’s shirt during the show, Malone said, “Come up to the front, ladies and gentlemen, we’ll sign that shirt. And f**k cancer!” Post met with Ava again after the show, as her parents told the music superstar that Ava has been undergoing chemotherapy since she was two, and they would suggest listening to Elmo during her treatment. But Ava insisted on listening to Post Malone instead. “Elmo fell off, kinda,” Posty joked, as he shared a special moment with Ava and her parents that none of them will likely ever forget. (Holler)
