Amanda Seyfried Will Host "Saturday Night Live" on Dec. 5

Amanda Seyfried will make her hosting debut on "Saturday Night Live" on Dec. 5, and Don Toliver will be the musical guest that night. Variety reported the booking on Nov. 15.

The show made the announcement on its own air first. A graphic shown during the Nov. 14 episode confirmed Seyfried's hosting slot, according to Variety. That episode was hosted by John Mulaney.

For viewers who have not followed the show closely, a few terms help. The host is the actor or performer who fronts the episode. They open with a monologue, which is a short speech to the audience, and then appear in the comedy sketches that make up most of the hour. The musical guest is the singer or band who performs during the broadcast, usually between sketches.

So the episode has two headline names. Seyfried is the host, and Toliver is the musical guest. Both are booked for the same Saturday night broadcast.

The show airs live on NBC, so the Dec. 5 episode will go out in its usual late-night slot. Anyone planning to watch can mark that Saturday on the calendar now. Nothing further has been announced for that episode.

The booking follows a regular pattern. The show lines up a host and a musical guest for each episode, and it often confirms them in the weeks before a broadcast. Mulaney's appearance on Nov. 14 was the most recent example of that cycle, and Seyfried's slot is the next one on the schedule.
