Heidi Gardner has taken her final bow on the Saturday Night Live stage and will not be returning for season 51. The comedian, 42, is exiting SNL after eight seasons, according to multiple outlets. Gardner, for her part, still has SNL's official Instagram handle listed in her social media bio and has not publicly announced her departure. Us Weekly reached out to NBC for comment. Gardner's alleged exit comes after Devon Walker and Emil Wakim confirmed their respective departures. It was reported earlier on Thursday that Michael Longfellow would also not be back for another season.
