Photo Call For Columbia Pictures' "Passengers"Chris Pratt and Jennifer Lawrence are two of our most cherished celebs, both as delightful as they are talented. So it should come as no surprise, then, that the "Passengers" co-stars get along swimmingly offscreen, too. But what if they're forced to hurl insults at each other? Well, then anything goes.

That's the concept of this clip from BBC One, called Playground Insults, in which actors are forced to sit across from each other and say the worst things about the other that they can imagine. It's all in good fun, of course, but there are certainly some truth bombs hiding among the clever barbs, and as you'll see in Pratt and Lawrence's case, the gloves definitely come off and things get mighty personal between the pair.

Everything from their shared superhero past ("How does it feel being in the stupidest Marvel movie?" Pratt asks Lawrence) to their humble beginnings on TV ("'I really loved you in "Everwood"'...said no one, ever," Lawrence tells Pratt) gets dredged up, with the actor offering some snide remarks about the actress's hair extensions, and the 26-year-old Lawrence getting in a few good digs about 37-year-old Pratt's age. But Pratt is clearly the master of this game, with some truly LOL-worthy comments ("I recently told you that you act like Adele sings. I hate Adele."), including a savage comeback about their "Passengers" sex scene.

Check it out for yourself and just try to keep a straight face. As both Pratt and Lawrence learn, it's impossible.
