'SNL' Books Arcade Fire, Miley Cyrus and Katy Perry to Kick Off Season 39

"Saturday Night Live" is kicking off its 39th season with a trio of major musical guests. 

Canadian alt-rockers Arcade Fire will grace the Sept. 28 premiere, and will have their performances (presumably songs from new album "Reflektor") introduced by host Tina Fey. This will mark their third appearance on the NBC staple.

For episode two on Oct. 5, Miley Cyrus is set to host for a second time, as well as provide the music. The twerk-happy pop star will likely perform her new fast-rising single, "Wrecking Ball" (No. 14 in its second week on Hot 100).

She last hosted in March 2011, in which she rolled out impressions of Fergie, Justin Bieber and Lindsay Lohan. "SNL" writers are probably writing a "Miley Cyrus Show" sketch -- in which Vanessa Bayer plays Cyrus and the real Miley portrays someone else -- as we speak.

But the biggest pop star of the moment is being saved for the third episode, when Katy Perry will be musical guest for the first time since September 2010. She hosted in December 2011, though Robyn took care of the music. Perry is feeling good these days after her "Roar" knocked Robin Thicke's "Blurred Lines" from the top spot on the Hot 100.
