"I will have to search harder and start developing things that I love, because there's no other choice. There will be ups and downs, but with my children, I know that I will have two more passengers along for the ride who are there to help me out," Shue told Rolling Stone recently.
Brenneman, 36, was first noted in her nude scene as detective Janice Licalsi during the first season of the ABC police drama NYPD Blue. The actress recently appeared in the ensemble piece Things You Can Tell Just by Looking at Her with Glenn Close and Cameron Diaz, which debuted at last year's Cannes Film Festival.
In other baby-related news, Grammy Award-winner Shania Twain and husband, rock producer Robert ``Mutt'' Lange, are preparing for parenthood as well.
``Yes, Shania and her husband are expecting their first child,'' Samantha Johnson, Twain's spokeswoman at Universal Music Canada, confirmed, adding that she had no other details.
Twain, 35, is one of the best-selling female singers in history, with combined worldwide album sales of about 50 million.
The couple lives in Switzerland where Twain is also currently working on her fourth album, Johnson said.
