'SNL': Colin Jost Appears in Fiancee Scarlett Johansson's 'Avengers'-Themed Monologue

Scarlett Johansson hosted NBC's Saturday Night Live for the sixth time, and her monologue spoofed The Avengers.

Aidy Bryant appeared in a holiday costume, and as she was talking, she suddenly began to disappear. Gradually, other castmembers started dissolving as if killed by Avengers villain Thanos.

"First Asian castmember and you guys are dusting me? Twitter is going to eat you alive," Bowen Yang screamed as he dissolved.

Beck Bennett came out and questioned why they were doing a monologue that didn't feel timely. Eventually, Colin Jost, SNL head writer and Johansson's fiance, showed up, thinking she'd be relieved to see him.

"Am I going to have to save everyone? I left my Black Widow costume in the car," Johansson declared amid the frenzied situation.

When Kenan Thompson came out dressed like Nick Fury, Johansson asked who he was. "Do you not watch the movies?" Jost asked.

They then learned that Pete Davidson was wearing an enormous Thanos glove and causing spectacular mayhem around the studio.

After the bit was done, Johansson thanked the audience and said she met the love of her life at the show, embracing Jost.
