Bad habits are hard to break — just ask potty mouth Charlize Theron.

When asked by MTV News if she's been able to tone down her colorful language since adopting son Jackson in March, the 36-year-old Snow White and the Huntsman star laughed and shook her head.

"A lot of people have sent me these children's books, and there's this amazing book, a best-seller called Go the F-ck to Sleep," she said. "This book was good for me because it made me realize that I don't need to judge myself right now."

Written by Adam Mansbach, Go the F-ck to Sleep has been called "a parenting zeitgeist" by The Washington Post and "a new Bible for weary parents" by The New York Times. For Theron, it's been a breath of fresh air.

"The whole book is just basically, 'Please, go the f— to sleep," she explained to MTV News. "Because [Jackson] doesn't understand anything right now, and so he just wants my face to look a certain way."

Theron also spoke about the joys of motherhood — diaper duty included! — on Today Tuesday. "I love it! I've got to tell you, I'm available for other babies' diapers to be changed. I can do it in my sleep now," the Oscar winner bragged. "I'm so good."

"As we were traveling, I had to buy diapers in different countries — because he came on the press tour with me — so I now know how to change a Japanese diaper, a Spanish diaper, an English diaper, German diaper," Theron added. "They all have little things [that are different]. I'm, like, the diaper pro now!"
