Julia Roberts Says She Has Dropped F-Bomb In Front Of Her Kids, Once

America’s sweetheart, Julia Roberts, is not perfect – and now she is proving that she is actually human after she told David Letterman she has, on one occasion, dropped the F-bomb in front of her kids.

Roberts is mother to 9-year-old twins Hazel and Phinnaeus, and 6-year-old Henry, who don’t know that she and their dad work for the movie industry and have never seen one of her films or posters.

Making an appearance on The Late Show With David Letterman, Julia Roberts also squashed rumors that she is pregnant.

Letterman asked her if she would be having more kids:

“Have you thought about adding more to the group? Any chance?” he asked.

“No,” replied the 46-year-old star. There, end of discussion.

Julia Roberts recently revealed she has avoided using foul language ever since becoming a mother. The Award winning star told PEOPLE at the Weinstein Company’s New York premiere of her latest drama, August: Osage County on Thursday:

“In the nine years of being a mother, I’ve only done that one time, and it brought all of us to a screeching halt. Everyone was like, ‘What just happened?’ It was horrible! I still think about it now, and I still can’t believe I did that. The children just stopped, and I said, ‘I am very sorry!'”

In her new role, Julia Roberts curses like there’s no tomorrow and drops obscenity after obscenity without batting an eyelash.

So what prompted the circumspect mom to utter the dreaded word?

“It was a traffic thing,” she said. “Somebody cut me off, and I was like, ‘f***’ It was dangerous. The children and I could have been hurt. Then I told them, ‘Mommy is so sorry,’ and we all just kept on going. We all recovered!”

Talking about her dinner table conversations with husband of 11 years, Danny Moder, 44, and their three children, Julia Roberts shares that they revolve around daily happenings in their lives and don’t resemble the scene in the film where she and Meryl Streep use a swear word every other time.

“Our conversations are so much happier than that,” Julia Roberts says. “I ask, ‘How’s school? Who has homework?’ It’s easy.”
