'The Voice' live shows: Adam Levine to use a charity swear jarAdd to Favorites | The Voice
This year, he's going to try to watch his mouth, and if he doesn't, it's going to cost him.
"I have a dirty mouth," he told People. "I curse a lot and I want to try to contain that a little bit." To encourage himself and his fellow coaches to mind their language, they're putting a swear jar next to the famous red chairs.
"I'll have a little curse jar next to me. Every time we say a bad word, $100 goes to charity. It will help us, it really will. Because we'll end up giving a lot!"
Blake Shelton's in on it, too. "I'm agreeing to it," he says. "I will sign up."
