Maggie Gyllenhaal and Peter Sarsgaard are expanding their family.
The actors are expecting their second child together, her rep confirms to PEOPLE.
“I just didn’t have a clue,” Gyllenhaal, 34, has said of motherhood.
“There’s no way to prepare for the challenges, the immense joys, the surprises, the disappointments and the shocks,” she said. “Your heart just rips open. It’s amazing.”
