CHRISTINA Applegate had to work hard to stay on script and stop herself swearing while making her latest children’s film.

The actress — who battled breast cancer in 2008 — said she had to make sure she never went off script at any point during voicing a character in Alvin and the Chipmunks: The Squeakquel – where she plays a member of the Chipettes, a singing group which gives the titular chipmunk gang serious competition.

“We’re strictly PG all the way,” she told Parade magazine. “When I improvise, foul things often come out of my mouth that aren’t on the page.

“So I really stuck to the script or there would have been some inappropriate words from my chipmunk. It was good to do something that was very wholesome.

“I don’t have any children, but I’m happy that I didn’t have to say anything disgusting in The Squeakquel that would shock kids.”

Christina, 38, also said mastering the high-pitched voice of her character took a surprising approach to get the right sound.

“You have to talk really slow like you just kind of had woken up from a nap,” she said. “It’s really funny because it’s as far away as you can get from that chipmunk sound. Then, you hear it sped up and it’s perfect.”
