Angelina Jolie: Pregnancy 'Great for the Sex Life'

Angelina Jolie and Brad Pitt have been inspired in the bedroom by her pregnancy.

"It's great for the sex life," the actress, who is expecting twins, told Entertainment Weekly. "It just makes you a lot more creative. So you have fun, and as a woman you're just so round and full."

She also said that she and Pitt, her partner and the father of their four children, were surprised to learn they were having twins.

She also said that she and Pitt, her partner and the father of their four children, were surprised to learn they were having twins.

"It did shock us, and we jumped to six [children] quickly," she told the magazine.

Jolie also said that her doctor ordered her to stop lifting the kids, so the couple has "worked out a system where Brad just lifts them to me every time they want to come up. I just don't bend down. I'll scream, 'Honey!'' and he'll come running."

She holds no hard feelings toward her "Kung Fu Panda" co-star Jack Black, who revealed on national television that she was expecting twins.

"Poor Jack! Immediately when he saw Brad, he apologized. But we both told him very clearly that we had only waited because ... you wait until all results are in on their health, and that we were past that point and if somebody had asked me directly, I would have said yes."

So why haven't she and Pitt tied the knot?

"It's not a big intentional thing not to marry," Jolie said. "We immediately were a family when we became a couple, and children were the priority, and we're both legally committed to the children."

Pitt's most recent gift to Jolie? A gun-charm necklace designed by their son Maddox.

''Mad, our 6-year-old, draws lots of war scenarios,'' she explains. ''He's all into war and guns. So for Mother's Day he drew a machine gun, and Brad had it made into a necklace, which is really sweet. It's really cute. I think it's really good!''

If six kids become too much, Jolie and Pitt certainly have enough money to pay for more assistance. Jolie just took the third spot on Forbes' annual Celebrity 100 list, due to the $14 million she earned in the last 12-month period, and Pitt, who earned $10 million, is ranked tenth.
