We knew we'd be hearing something this week, but NBC has unloaded.

The Peacock confirmed Tina Fey will host Saturday Night Live's season premiere on Sept. 28, joined by Arcade Fire as musical guests.

Meanwhile, Miley Cyrus (you know they moved heaven and earth to make this happen!) will host and perform on Oct. 5, with Bruce Willis and Katy Perry reigning over the following week (Oct. 12).

More details are sure to emerge, as we also watch for casting updates.
