Scarlett Johansson was on the receiving end of a messy prank during the MTV Movie and TV Awards on Sunday night.

The "Avengers: Endgame" star, 36, was rattling off her acceptance speech after winning the generation award when her husband, "Saturday Night Live" star Colin Jost dumped a bowl of bright green slime on his wife’s head.

She paused, shocked before saying: "What the f---?"

"MTV!" responded the "Weekend Update" host. "You got slimed!"

"That’s Nickelodeon," she snapped back, referencing the Kids Choice Awards, which frequently sees celebrities get blasted with slime on stage.

Jost responded: "S---. I’m very, very sorry."

The comedian reached out to remove some of the goo from his wife’s hair prompting her to say: "Don’t touch me! Let me do it. Where did you even get this?"

"I love you, Amazon," Jost said.
