met the America's Got Talent
host after he performed at The Laugh Shop at Hotel Blackfoot in Calgary, Canada, earlier this month.
After the show, Royan, who wore a top that read Mariah
, met Cannon and passed on a card for his wife of four years.
"[He was] so kind! He said he would pass along my card to Mariah and took some time to get some photos
," says Royan. "So so nice!"
Royan, who works to raise awareness about organ donation, and Cannon, who has suffered from a lupus-like autoimmune disease
in the past, share a common ground in educating others about their respective causes.
"He shared about his kidney issues at the show ... I shared my project about organ donation
in my card!"
