Angelina Jolie is pregnant, a "close source" reportedly told Us Weekly magazine.

The flowing dress that Jolie wore to Sunday's SAG Awards — as well as her curvier body — had stargazers speculating that she might have a bun in the oven.

One SAG attendee told Us Weekly: "It was so obvious she was pregnant. You could clearly see the bump's outline."

Pitt, 44, and Jolie, 32, have four children: Maddox, 6, Pax, 4, Zahara, 3, and Shiloh, 19 months.

Jolie's estranged father, Jon Voight, recently said, "It's wonderful news ... if that's true."

A rep for Jolie did not immediately respond to FOXNews.com's request for comment.
