The insider says:
"She’s been secretly filling her pals in on the good news since last week,” an insider tells. “Britney is in shock herself, this definitely wasn’t planned. But she’s thrilled just the same.” As for her other two kids: “She feels like she’s raising her boys on her own and doing a fine job. Forget all the rehab drama. Brit’s stronger now and being a great mother.”
Seriously.. I bet she bets Angelina with the number of kids. I'm sure they will all grow up completely normal and not addicted to drugs or anything.
