Angelina Jolie and Brad Pitt
The day after unveiling her baby bump
at the Film Independent's Spirit Awards, Angelina Jolie
spent Oscar night at home, relaxing.
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."
