For the first time since 1989, the Academy Awards will have no host.
Since Kevin Hart was selected and then stepped down after an old 'Tweet' controversy, the Oscars have not announced a replacement.
According to Variety, the show will use a new format with stars introducing various segments.
The 91st Oscars® will be held on Sunday, February 24, 2019, at the Dolby Theatre® at Hollywood & Highland Center® in Hollywood, and will be televised live on the ABC Television Network.
