Maggie Gyllenhaal & Peter Sarsgaard Know The Baby's Gender

Soon-to-be big sister Ramona was spotted strolling to school in Brooklyn, New York yesterday morning with her mom Maggie Gyllenhall (January 7). With their second baby on the way, Ramona's dad Peter Sarsgaard recently admitted that he's not too sure how his 5-year-old daughter will react to having a sibling.

"I've seen kids with siblings - I don't have any siblings, so I don't know - but they generally go for about 5 minutes, 'Oh, cool! Anyways, what are we going to do now? Can we return it?" Peter said at this week's Jay-Z concert in NYC, joking that Ramona "doesn't know what she's in for."

"I think it gets boring quickly, at first, and it takes a while for them to bond," he added.

The Lovelace actor also revealed that he and Maggie know the gender of the baby on the way - but it seems they're keeping the big news to themselves for now.

"It's the nice thing about knowing the gender of the child," he says. "You don't have to call it 'it,' which gets really weird after seven months in. So we've been trying out a few names, but nothing solid."
