The 38-year-old, who raises Lily, 13, with former partner Michael Sheen, said she wants to set a good example and chooses projects based on how they will affect the young girl, reported Showbizspy.
"Well, I haven't done an awful lot of nude scenes. And I've been somebody who has had a child for a very long time. Most of my peers don't have a 13-year-old. And it's embarrassing.
"My daughter said to me, 'You know, I'd really love it if you never said the cuss words in an interview again'. Whoops. I've just done it," she said.
The actress recently said she'd like to have another baby.
"There's absolutely part of me that goes, I'd love to have a baby in the relationship I'm in, and have that experience when the relationship's really good and exclusive, but I'm just not sure," she added.
