Elizabeth Banks "curses like a sailor".
The 'Hunger Games: Catching Fire' star admits to overusing cuss words, but she can't stop herself, despite having a sons, Felix, two, and Magnus, 12 months, with husband Max Handelman.
She told People magazine: "I curse like a sailor. My kids love this Mumford & Sons song, 'Little Lion Man', and it has the F-word. We just play it like it's not big deal. We call them grown-up words, and mummy uses a lot of them."
The actress is also fond of drinking, but admits it can lead to some nasty bruises.
She added: "I get mystery bruises all the time. Usually after I've been out drinking. Bill Murray referred to them as badges of honour, and that's a nice way to think about it!"
While she may have some bad habits, Elizabeth is a dab hand with a paintbrush.
She explained: "I personally painted the ceiling of my guest bedroom a bright blue. It's this cute little room with Woods wallpaper, so I thought it needed it."
