Mila Kunis, who is now expecting her second child with husband Ashton Kutcher, says she isn't rushing back to acting, but couldn't resist the opportunity to co-star in Bad Moms.

It all kind of happened very serendipitously," Kunis said during a recent AOL Build discussion about the film in New York.

So, this is the only movie I did between Baby 1 and 2," the 32-year-old actress explained. "I never gave myself a timeline. I said, 'I'm going to go back as far as acting is concerned, when I am ready, when I find the right project, when the time is right.

Kunis then recalled how a friend passed her the script for Bad Moms when her daughter Wyatt was about 3 months old and, although she said she devoured it as if it was a good book, she insisted she didn't consider it as the source of a possible job
