Stone among stars to hand out Oscars
Mahershala Ali, Emma Stone and Viola Davis have been confirmed as presenters for this year's Oscars.
The three Hollywood stars were the winners of the acting categories at last year's awards - Stone won best actress for La La Land, Ali won best supporting actor for Moonlight and Davis won best supporting actress for Fences.
Best actor winner Casey Affleck was already known to not be attending. The Manchester By The Sea star would have been expected to present the best actress award, according to the show's tradition, but in January he withdrew from the hosting role.
Chadwick Boseman, Laura Dern, Jennifer Garner, Greta Gerwig, Tiffany Haddish, Tom Holland, Kumail Nanjiani, Margot Robbie and Daniela Vega have also been confirmed to be presenting awards.
Jimmy Kimmel will host the 90th Academy Awards from Hollywood's Dolby Theatre on March 4.
