Chris Rock to host 'SNL'

Old home week continues at "Saturday Night Live," when Chris Rock returns for one night only on Nov. 1; Bill Hader was host this past Saturday, so that deja-vu-all-over-again sensation we've all been experiencing now has an official explanation.

Rock was a cast member from 1991 to 1993, and has been gainfully employed ever since: His "Top Five," which he wrote/directed/stars in, arrives at a theater near you on Dec. 12.

And Jim Carrey... He will host "SNL" (for the third time) on Oct. 25. ("Dumb and Dumber To" is in theaters the week after.) 

Also: Iggy Azalea will be on the Carrey show, "SNL" just said. That will mark her "SNL" debut. And Prince -- for the third time -- will be the musical guest on Rock's show.
