The Weeknd -- the newly very-hot alt-R&B act from Canada, and someone otherwise known as Abel Tesfaye -- will be a musical guest on "Saturday Night Live" in the new season.

But he's not actually the biggest news: Someone called Miley Cyrus will appear as both guest host and musical guest...

(And Demi Lovato.)   

All this was just announced, and -- other than Kanye and Nicki MInaj -- this all does mostly sound like a repeat of Sunday's "VMA's."

Cyrus -- by the way -- is not the first pop star to double up as both guest host and musical guest on "SNL." In fact it's reasonably common, although it is a good barometer of cultural hotness:

Others include Drake ('14), Blake Shelton (in January), Bruno Mars ('12) and Justin Timberlake, who is the doubles champ, in '03, '06, and '13. Here SNL's 41st season first three weeks' lineup, straight from the news release:
