The Changeling star and partner Brad Pitt, who have recently dropped hints that they would like another baby, are said to be expecting a seventh addition to their brood.
And a report in US magazine OK! says that Angelina is thrilled.
A source told the mag: "Angelina is really savouring every moment. She`s having a tough time with morning sickness but says it`s all worth it."
There was no sign of a baby bump when the elegant actress posed in a figure-hugging Atelier Versace gown at the Golden Globes on Sunday.
But the doting parents - who already have adopted children Maddox, ten, Pax, eight, and Zahara, six and biological children Shiloh, five, and three-year-old twins Knox and Vivienne - are said to be decorating a nursery already.
In a recent interview Angelina said she and Brad had not ruled out having more children.
And she added: "Nothing planned at the moment, but we just don`t know. I could end up pregnant."
She also revealed that the Tree Of Life star had taught her to appreciate the strong bonds of a loving family.
She said: "I suppose what I`ve learned from Brad is to be able to have the kind of family whose happiness and well-being comes before your own," she says in the interview.
"I`m very, very grateful to have such a loving family, and I wouldn`t have that without him."
