Another thing we love about Jennifer Lawrence is her brutal honesty, even if it means having to admit to some unfortunate truths about herself. When asked about what her nickname on set was, Jennifer responded that they called her ‘Katpiss Never-Clean.’ Apparently, she would often show up with the same blood and dirt from the previous day because she was too tired to shower after the long hours of shooting.
That explains the ‘Never-Clean’ part but why ‘Katpiss’ asks Josh. From Josh’s expression, it’s clear that he knew the answer but wanted to put her on the spot anyway. She sheepishly revealed that it was because she peed in the woods. Naughty, naughty Josh!
