It's been rumored for about a month that Maggie Gyllenhaal, 34, may be expecting a new addition to the family, since photographs emerged in the news of what appeared to be the actress sporting a tiny baby bump.

Now the whispers have been confirmed, as the Hysteria actress and hubby Peter Sarsgaard, 40, announced that they are expecting their second child, confirms Us Weekly. The Brooklynites shared the good news with their families, including bro Jake Gyllenhaal, over the Thanksgiving holiday. She is about four months along in her pregnancy, a source told the magazine.

This will be the second child for the couple, whose daughter, Ramona, is 5. Gyllenhaal learned about the demands of motherhood her first time around. "Before my daughter was born, I was all, 'I'm only going to feed her organic food, I'm only going to give her cloth diapers,'" she told Marie Claire about her noble parenting intentions. "And then, once you have a real child who is starving on a plane, you give them a bag of potato chips because that's all there is, and they're OK and it's fine."

You can next catch Gyllenhall, sans baby bump, in the family-centric Learning to Fly, a film about two moms who team up to make a difference at a high school. You can catch Hysteria currently out in theaters. Sarsgaard will next appar in the 2012 drama, Night Moves.
