United Kingdom, July 28 -- Dax Shepard allows his kids to swear.

The 50-year-old actor - who has daughters Lincoln, 12, and Delta, ten, with actress Kristen Bell - has revealed that he has no issues with swearing in front of his children, and he doesn't mind them cursing "when it's called for" either.

Dax said on the Armchair Expert podcast: "I fully swear in front of my kids. They are allowed to swear, not with impunity, but when it's called for, and they land it, and it's in the house and not out at a restaurant, it's OK.

"My defence of it is, I just told the girls, like, 'Hey, these are noises that come out of your mouth, and you assign what they mean to you.'"

Dax also acknowledged that his kids are exposed to curse words at schoo...
