Chris Hemsworth and Scarlett Johansson didn't hold back when they were challenged to hurl personal insults at each other.
The two Avengers: Endgame stars stopped by BBC Radio 1 to play a game of 'Playground Insults' and took it in turns to abuse one another.
Johansson's insults were relatively tame and she mostly poked fun at Hemsworth's outrageous physique.
"Chris, you're ugly," Johansson said. "Everyone's been talking about it. You're just really ugly."

The actress who plays Black Widow also had a crack at Hemsworth's clothes, saying: "You've got a growing collection of grandma cardigans and I've been meaning to talk to you about it. It's cray."
Hemsworth's insults were way harsher with the Thor star mocking Johansson's intelligence.
"It's lucky you're beautiful because there's nothing up here," he said, pointing to his head.
"Wow, that's mean," a shocked Johansson said. "Did you just call me dumb? You went straight to dumb?"
He continued, "Do you even know how to spell your name, because no one else does."
"That cut deep," Johansson joked.
