Selena Gomez — who made a guest appearance on “Saturday Night Live” — also popped by the show’s afterparty at swank L’Avenue at Saks.

A spy tells us the singer was the first to arrive at the bash, and dined with a group of her friends before “bouncing back and forth” between the tables of the night’s “SNL” hosts, Steve Martin and Martin Short.

Gomez stars in Hulu’s “Only Murderers in the Building” with the comedians.

Gomez — in the same Valentino Pink PP collection look she sported during a sketch on the NBC show — took off her sky-high pink platform pumps mid-bash in favor of a pair of boots, says a spy.

We hear that Martin, who was celebrating hosting the show for the 17th time, attended the party with his wife Anne Stringfield.

Short, who was hosting for the 4th time, arrived at the bash Paul Rudd and Adam Scott. Musical guest Brandi Carlile was also on the scene, getting congrats from well-wishers.

Also at the party was “SNL” head Lorne Michaels — who we hear was hanging out with film director Steven Spielberg — plus cast members Colin Jost, Bowen Yang, Chloe Fineman, Heidi Gardner, Ego Nwodim, Sarah Sherman, Molly Kearney, Michael Longfellow, and Mikey Day.

Mariska Hargitay, Nick Kroll, Kieran Culkin, Eric Andre, Ava Max, Zoey Deutch and Jesse Williams were also see at the celebration.

Next week’s host, “Elvis” star Austin Butler, was there, “keeping a low profile,” says a spy who noted he was sitting in a back corner in a black hat.
