Jolie, 32, and Brad Pitt, 44, were at home in Los Angeles with the kids and enjoyed the relative peace and quiet, a source tells PEOPLE.
Though neither was at the Oscar ceremony, their absence didn't stop the show's host, Jon Stewart, from including Jolie in a joke about pregnant actresses, saying, "Obviously, Angelina Jolie couldn't be here – it's hard to find 17 babysitters on Oscar night."
The growing Jolie-Pitt family currently includes Maddox, 6, Pax, 4, and Zahara, 3, and Shiloh, 1. A source close to the couple says they are "thrilled to be adding to their brood."
