The comedian and actor appeared on "Good Morning America" Wednesday and told host Michael Strahan "no" when asked if he will helm the Academy Awards on Feb. 24.
Hart stepped down Dec. 7 from hosting the Oscars — just two days after announcing he would host — after homophobic comments surfaced that he made years ago.
Hart, who had recently apologized on his SiriusXM radio show for the comments and tweets — made between 2009 and 2011 — said Wednesday that he's "done" apologizing.
"I'm over it," he told Strahan. "There's no more conversation about it ... I'm over that, I'm over the moment ... I'm not giving no more explanation of who I am ... I'm just done. If you didn't (hear the apology), then I don't know what you're looking for."
Hart, who is making TV appearances to plug his new movie, "The Upside," told DeGeneres he was "evaluating" his decision.
That interview received some backlash and CNN's Don Lemon called Hart out on his show for giving an "insincere" apology.
CNN has reached out to Hart's representatives for comment.
The Academy has yet to comment on who will take Hart's place or if the awards show will go without a host this year.
