Host Charli XCX — along with cast members Heidi Gardner, Ego Nwodim, and Sarah Sherman — performed a baby shower-themed version of the singer’s “Hot To Go,” about a fling that their best friend and expecting mother (played by Chloe Fineman) had with a man named Domingo during her baby moon, which she took with her friends instead of her husband.

"D-O-M-I-N-G-O / Kelsey's texting Domingo / Thought that she forgot that dude / She's sending him her pregnant nudes!"

There was exclusive merch. There were many It Girls. There was lots of Brat green. Charli XCX pulled double-duty on SNL on Saturday, her third time as musical guest and her first time hosting. She performed Brat highlights “360” (introduced by Julia Fox) and “Sympathy Is A Knife” and starred in a bunch of sketches.

The Kel Squad is back — this time featuring Charli XCX — with a "HOT TO GO!" parody that reveals some surprising paternity info.
