Her husband Josh Kelley worries that their baby will pick up her swearing habit and has told her to watch what she says.
Katherine Heigl's foul mouth has landed her in trouble with husband Josh Kelley - because he's worried their baby daughter is picking up her swearing habit. The couple adopted little Naleigh from South Korea last year in September and Heigl admits becoming a parent has been a major adjustment.
But right now her biggest challenge is curbing her filthy language in front of the baby girl - and she's under serious pressure from singer Kelley to watch what she says.
She explains, "It's a big problem. My husband's been on my case. I have a bit of a truck (or) sailor (mouth)... It's been pretty bad since I was little and I picked it up from my parents. I do like the dirty jokes, I don't tell them around her though."
