Is Angelina Jolie too skinny to have another baby?

Is there trouble in paradise? Could Angelina Jolie be "too thin"? Is she the subject of the drug rumors circulating around Hollywood? Where is my coffee? I know I had it here somewhere.....

The frail actress fears her family will be destroyed by her weight loss and a persistent drug rumour
Angelina Jolie has become so skinny she's petrified she'll never be able to conceive another baby.
Insiders say the actress is increasingly worried her extreme weight loss might prevent her adding to her young family — and destroy her relationship with Brad Pitt in the process.
Sources say after months of being bony, the star has slipped into a deep depression about her weight, and there are days she can barely get out of bed.
"Ange is panicking she can't have any more biological kids because she's too thin," says a source. "She's skinnier than she's ever been in her entire life. But the more she worries and frets, the more weight she loses.
"She desperately wants more kids with Brad, but knows she'll never have another kid if she doesn't get a grip on her eating issues. So now she's terrified they'll never be able to add to the family and that will force her and Brad apart."
Adding to Ange's distress is a persistent rumour circulating about a female celebrity who's using drugs.
