2:48 PM PT -- According to Deadline, Pete isn't the only one to say goodbye the show ... Kate McKinnon, AidyBryant and Kyle Mooney are all also leaving.
Looks like Pete Davidson is making some big changes ... there's a report he's expected to leave "Saturday Night Live" after this weekend.
That's right, according to Variety, Pete's final show will come after Saturday's finale. It's a pivotal move for the 28-year-old comedian. PD joined the show back in 2014, when he was just 20 years old ... as one of the youngest cast members in the show's history. Now, he's amongst the long-serving performers.
