Brangelina's Baby Appetite is Insatiable, In Vitro

Turns out, Brad Pitt and Angelina Jolie really are as neurotic about this whole 'expanding their family' thing as you may have suspected.

The couple used in vitro to conceive those two twins Angie just popped out, Us Weekly is reporting, and not because Angie couldn't get pregnant.  They just really, really wanted twins. Fast.

• ' "They conceived through in vitro fertilization," a well-placed source within their camp tells Us. "They both desperately wanted more babies soon."
• 
  
• The chance of having fraternal twins at Angelina's age (33) naturally is under 1 percent; with in vitro, the chances are 25 percent. Says Dr. Arthur Wisot of L.A.'s Reproductive Medical Group (who did not treat the couple), "We live in an era of reproductive freedom, so anybody can do anything they want within legal limits."
• 
  
• The actress chose the procedure (which can cost around $12,000 a pop) so "she wouldn't have to deal with the stress of trying to get pregnant," the source tells Us. "She could just knock it out."'

Angelina Jolie was once addicted to drugs.  Then cutting herself, violent sex, and tattoos.  Doctors say compulsive behavior never really goes away, it just turns into something else.  I think you know where I'm going with this...

I mean, fourteen kids?  Really??
