Hart appeared this morning on ABC, the Oscars network, to confirm on Good Morning America that he won't return as host of the 91st Academy Awards after telling Ellen DeGeneres last week that he'd reconsider his decision to step down. "There's no more conversation about it ... I'm over that, I'm over the moment," Hart said in an interview with Michael Strahan. Hart said it's already too late to prepare to host the Oscars. "It's hard to predict what can happen. I don't want people to think there's a thing about me and the Academy," he added. Hart, who apologized again Monday for his past homophobic comments in a SiriusXM radio interview, also said he's done apologizing for his past homophobic comments, adding that he has "said everything I can possibly say." "I'm not giving no more explanation of who I am," he said. "I'm just done."
