Don't expect to see Pete Davidson at Kourtney Kardashian and Travis Barker's wedding this weekend.

Davidson's girlfriend Kim Kardashian will be in Italy on Saturday to attend her sister's wedding to Barker — but a source tells PEOPLE Davidson is "expected to be at SNL."

This weekend, Saturday Night Live's season 47 finale features host Natasha Lyonne and alternative pop band Japanese Breakfast as musical guest.

According to Variety, Davidson is expected to leave the NBC sketch comedy after this season.

Davidson joined SNL in 2014 at the age of 20, making him one of the youngest cast members to ever appear on the show.

He gained attention for his standup chops during "Weekend Update" segment

and went on to star in an eclectic roster of films including The King of Staten Island and Suicide Squad.

Next, the Staten Island native is gearing up to star in A24's upcoming dark comedy-horror flick Bodies Bodies Bodie

and opposite Edie Falco in the Peacock series Bupkis.

The actor will also serve as a writer and executive producer on the sitcom, which is loosely based on his own life.
