Amid rumors that Angelina Jolie, 32, is expecting twins, a close source confirms to Us Weekly that the actress is indeed pregnant.

One SAG (Screen Actors Guild Awards) attendee tells Us in its latest issue, "It was so obvious she was pregnant. You could clearly see the bump's outline."

The source reveals Jolie may sell the confirmation, with the money going to charity.

Reps for Jolie and Brad Pitt, 44, refused to comment.

The couple have four children: Maddox, 6, Pax, 4, Zahara, 3, and Shiloh, 19 months, whom Jolie gave birth to in May 2006.
