Exhausted Jolie struggles with twin demands

While Brad Pitt is out and about, hopping between film festivals to promote his latest flick, “Burn After Reading,” Angelina Jolie has remained in near-seclusion at their French home since giving birth to twins in July.

According to recent reports, the actress is so exhausted she's unable to play with her children, much less join her partner's publicity blitz.

“(Angie's) been staying in bed most of the time,” a friend told In Touch. “All she does is nap. She has little or no appetite and has to force herself to remember to eat because she is still breast-feeding.”

The friend explained that Angelina is showing signs of what may be postpartum depression, as she “cries at the drop of a hat and laughs at inappropriate times,” but another insider disagrees.

It's simply a case of severe fatigue that has the “Wanted” star down, a close source revealed to Star magazine. Raising six children, breast-feeding two of them, and recovering from a c-section is enough to drain anyone, after all.

“Angie feels so weak and uncomfortable that she can't even sit on the ground and play Barbies with Zahara and Shiloh,” the source said. “She wants to be able to run around and play with her older kids.”
