Chris Pratt, Jennifer Lawrence hurl hurtful insults at each other

Jennifer Lawrence and Chris Pratt face off in a round of Playground Insults.

Jennifer Lawrence and Chris Pratt like each other ... we think.

The stars of upcoming sci-fi blockbuster Passengers are on the publicity trail for their new film, and are using it as opportunity to prank each other at the drop of a hat.

In an interview for BBC Radio 1, the pair were given an unusual task - to sit opposite each other and hurl the most hurtful, personal insults they could come up with. The first person to break down in a fit of laughter (or tears) would be deemed the loser.

The challenge seemed to come remarkably easily to both stars - although Pratt pulled out in front from the very start, opening with this sick burn referencing Lawrence's 2015 Oscar-nominated Joy Mangano biopic:

" ... Why did they call it Joy?"

From there, the pair traded an escalating series of brutal barbs, with Pratt's poker face proving particularly hard to beat.

"It's such a shame ... to meet somebody ... you thought you'd like," he told his co-star at one point.

"You are so falsely strong that if I was given a choice between you and your wife to protect me, I would chose Ana [Faris]," Lawrence said through frequent giggles.

Pratt fired back with: "I recently told you that you act like Adele sings. I hate Adele."

"Where do you keep your Oscar?" Lawrence deadpanned.

In the end, Pratt won, offering up a filthy quip about his experience finishing their Passengers sex scene that doesn't bear repeating (and earns the clip below a strong language warning).
