Jennifer Lawrence and Chris Pratt recently shared some 'not-so-nice thoughts' about each other. During the promotion of their upcoming sci-fi flick, the Passengers actors sat down for a round of Playground Insults, a game conceptualised by BBC Radio 1 that puts celebs against each other to see who can crack the other one up with personal slights first.

The Passengers duo became best pals during the movie's shoot, but in the recent BBC Playground Insults, the pair was given a tough task — to sit opposite and hurl horrible insult at each other they could come up with. The first person to break down in a fit of laughter would be considered as the loser.

The challenge seemed to come as an extremely easy task to both the stars. The duo jabbed each other by every possible thing, from Lawrence's Joy to Pratt's lack of an Oscar to their intimate scene in the Passengers.

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

From there, the pair roasted the hell out of each other that they could barely keep a straight face during the not-so-nice verbal battle.

"I recently told you that you act like Adele sings," Pratt declared in a later jab. "I hate Adele."

Calling out the 37-year-old actor's age, Lawrence went on insulting him, "You are so old that your publicist is a registered nurse."

The war of words led one thing to another and both the actors ended up insulting each other's performance during their sex scene in the movie.

"Before our sex scene, I took two Pepto Bismol," Lawrence quipped.

"During our sex scene, I felt your d**k rubbing into me," Pratt responded, leading Lawrence to burst into laughter. At the end, Pratt won the battle of words.

Passengers is slated to hit screen on December 21, 2016. Check out the clip below.
