Chris Pratt may be all smiles, but that usually just means he’s planning something. As Jennifer Lawrence told Jimmy Kimmel on Monday night, “it’s always a bad sign when Chris seems sincere about something.” Pratt has spent the entire Passengers press tour posting photos of himself and Lawrence on social media, but with his co-star cut out of the frame. After showing Lawrence all the proof, Kimmel asked her, “Are you going to do something about it?”

“F— it,” Lawrence responded. “I’m gonna do something about it.”

Kimmel and Lawrence proceeded to hunt down a bus with a gigantic Passengers ad, whereupon Lawrence unleashed a can of black spray paint on the picture of Pratt’s face. Kimmel helped out too, so that by the end, Pratt’s face was covered in black paint, with little red devil eyes and his name changed to “Rat.”
