A source tells Celebuzz that on Saturday, November 22, Spears will have her third go at hosting the sketch show.

Eight years ago, at 18 years old, Britney became the youngest person in history to both host and perform on the same episode.

Spears returned to play ringmaster to Saturday Night in 2002.

The cast of repertory players currently includes Andy Samberg, new mother Amy Poehler and Kristen Wiig.

None of them will be in quite so physically toned as Britney.

UPDATE:

Representatives from NBC have officially denied to Celebuzz that Britney Spears will either host or perform on the November 22 episode of Saturday Night Live.

Britney's own people have neither denied or confirmed rumors that she will be on the show.

However, Britney's new album, Circus, is due to drop next month; so from a marketing viewpoint, a brisk song and dance on Saturday Night would go a long way.

Plus New Music Tipsheet is not afraid to list Britney Spears as scheduled to appear on the November 22 SNL.

This story is still working.  Stay tuned for details as they develop.
