J-Law has swear jar on film set
Jennifer Lawrence has been given a swear jar on the Hunger Games set - to try and curb her foul mouth.
The 23-year-old actress' bad language on the set of the young adult action movie Mockingjay: Part 2 in Berlin have apparently cost her hundreds of pounds.
A fellow actor told The Sun newspaper: "Jen has the filthiest mouth. It's great but she's so easy to wind up so some people set up a swear jar for her.
"It's running and running, but it's not stopped her."
Michael Fassbender and James McAvoy, Jennifer's co-stars in X-Men: Days Of Future Past, have previously revealed she is prone to turning the air blue.
Michael said: "Her performances are intelligent and logical through what seems to be a natural intuition. She's aloof and intelligent. Oh, and she's got a filthy mouth!"
While James recalled seeing Jen being told off by her mother on set for swearing.
Kristen Stewart previously revealed she had a swear jar on the set of Twilight: Breaking Dawn to stop her dropping the F bomb.
