Cover Story: No More Babies for Angie!

They are reportedly heading to Ethiopa to add another orphan to their well-loved brood, but as Angelina Jolie and Brad Pitt await this seventh child, they're struggling with the news that they may never have another biological baby, sources say.

OK! has learned that because Angie's last two pregnancies were so fraught with complications, she has been advised to wait a long time before getting pregnant again – or not to get pregnant at all.

"Her previous pregnancies ended with emergency caesarian secions," an insider tells OK!. "She's been told that, at the least, she should not get pregnant for a year after her last deliver, and it would be safer if she did not get pregnant, ever."

The health complications this time around could pose a direct danger to the Changeling star, Dr. Larrian Gillespie, who has not treated Angie, tells OK!.

"Angelina is at risk of having a stroke or heart attack, and because she developed gestational diabetes, there is a high risk she'll have it again, with the child being at risk for diabetes."

Not being a biological mom again might be hard for Angelina, as she revealed to Vanity Fair last year that she loves being pregnant.

"It makes me feel like a woman," she said. "Also, I happen to be with someone who finds pregnancy very sexy."
