Update: Vulture reports that a spokesperson for "SNL" called TMZ's original story "'incredibly inaccurate,' adding, 'The season hasn’t even started and cast decisions aren’t made until the end of the season.'"

The 40th season of "Saturday Night Live" will be the last for one of its longest-running castmembers.

Kenan Thompson, who has been a mainstay of "SNL" since he first joined the cast in 2003, is leaving the show, according to TMZ.

Thompson started out as a featured player on "SNL," but quickly carved out a big niche for himself in the cast, popularizing fan favorite characters like Deandre Cole, host of "What Up With That?" (He even played MTV's own Sway.)

Thompson's last season will be his twelfth, meaning he will have not only the longest run of any African-American actor on the show (Tim Meadows was on for ten seasons), but he will end tied with Al Franken for the third-longest run of any person on the show, cementing his place in "SNL" history.

And don't worry about any behind-the-scenes drama: the split is apparently amicable, and TMZ says that he's "in talks for a new show and plans on moving to L.A." when the show ends.

Do we know what the next show will be? Unfortunately, not yet. Do we want the new show to be a "Kenan and Kel" reunion, or a new, gritty remake of "The Adventures of Superdude?" We do we do we do, oooh.
