Billy Crystal will be hosting the next Academy Awards ceremony.
The Oscars veteran said on Twitter that he is "doing the Oscars so the young woman in the pharmacy will stop asking my name when I pick up my prescriptions".
His appointment comes after Eddie Murphy quit following the departure of the show's producer in controversial circumstances.
The 63-year-old comedian last hosted the show in 2004. This will be his ninth stint as host.
The move to name Billy as Oscars host comes after a guest appearance on the 2011 show for which he received a standing ovation.
He said later he was moved by the warm reception and that "it might be fun" to host the show again.
"I think the show needs to change," he said in an interview in March.
"There's too many awards and it has to sort of freshen itself up, and if I can be a part of that, that would be great."
The past two ceremonies featured the duos of Anne Hathaway and James Franco and Steve Martin and Alec Baldwin.
Meanwhile, Hugh Jackman hosted solo in 2009.
