Saturday Night Live is doing it big for their final episodes of the year. John Cena and Casey Affleck will both make their SNL hosting debuts this month, NBC announced Friday. Cena will be joined by musical guest Maren Moris, while Affleck's episode will see the return of previous SNL champ Chance the Rapper.

Cena landed a proper comedic flex in last year's Trainwreck, joining star and writer Amy Schumer for a memorable sex scene that also happened to be awkward as hell. "It was originally written different," Cena told Larry King in April. "It was supposed to be an overly physical scene. Big guy, you know, 'I'm sick of being with this guy because he's too physical.' And then we got into a room and we started to ad-lib and both Amy Schumer and Judd Apatow were so receptive to the kind of twist I put on the character that we ditched all the physical humor and just made it a very uncomfortable scene."

Affleck is currently riding a wave of serious Oscar buzz surrounding his performance in Kenneth Lonergan's Manchester by the Sea. Earlier this year, he starred in Triple 9 alongside Norman Reedus and recreated a daring U.S. Coast Guard rescue in The Finest Hours.​

This week's SNL is hosted by Emma Stone, the star of this year's critical darling La La Land. The episode, which will see Stone joined by musical guest Shawn Mendes, marks her third time as host.
