"Saturday Night Live" announces December lineup. Professional wrestler John Cena is booked to host the NBC variety show on December 10 while Casey Affleck, hot on heels of his critically acclaimed movie "Manchester by the Sea", is set to serve as an emcee on December 17, AceShowbiz said.

Country breakout star Maren Morris is scheduled to perform during the Cena-hosted episode while Chance the Rapper is expected to be a musical guest a week later when Affleck comes to the show. It marks a hosting debut for both Cena and Affleck.

Before welcoming the wrestler and the actor, "SNL" will have Emma Stone first on December 3. The actress who becomes critics' darling for her performance in "La La Land" will return as a host. She is joined by musical guest Shawn Mendes.
