Mariah Carey left the cast of "Schitt's Creek" tongue-tied after she surprised the actors during YouTube's Dear Class of 2020 graduation special.
Eugene Levy, Catherine O'Hara, Daniel Levy and Annie Murphy – playing their beloved characters Johnny, Moira, David and Alexis Rose – came together virtually to sing Carey's iconic song "Hero" in honor of all the teachers and students who have prevailed during the pandemic.
Then, the Grammy winner jumped in, a fan blowing her hair and all. "Moira, darling, I hope you didn't mind that I jumped in like that," Carey said as the other characters gasped. "You all sounded so good that I had to get in on it." Daniel, as David, yelled, "I think I'm having a heart attack!" Carey also sent her own message.
