(Cover) - EN Showbiz - Sarah Jessica Parker "grossed out" a film director by admitting there was a breakout of head lice at her son's school.

The actress is promoting new movie I Don't Know How She Does It, in which she plays a woman who has to juggle a busy career with being a mother. It's a topic the star is familiar with as she has three children, James Wilkie, eight, and two-year-old twins Marion and Tabitha, with her husband Matthew Broderick.

In the movie, Sarah's character Kate is horrified to hear her child's school is plagued with head lice. She had first-hand experience of the situation having received a letter saying the same thing during shooting.

"I had to send it to Doug McGrath, our director, who was, of course, repulsed and grossed-out and terrified to be near me because he knows our son creeps into our bed and likely shares a pillow and likely shares lice," she laughed to Extra. "I'm happy to report my son has yet to find friendly critters."

In a separate interview, Sarah Jessica discussed the likelihood of another Sex and the City movie. There have been two so far, with the most recent 2010 release panned by critics. The actress remains faithful to the franchise, although she is unsure whether more will be made.

"I don't know of a movie in the imminent, or near, or even distant future," she told Access Hollywood. "I've always trusted that we've had a sense of when that timing, what is the right timing for a movie.

"Honestly, I'm not being cagey. There is no discussion currently of a Sex and The City 3. Do I hold it out in my future in some way as a possibility? Of course."
