When fetching his brother Pax, Maddox was seen throwing a tantrum (what is it with all these wealthy people) because he had to sit in the back seat of the car instead of sitting up front and driving the car like Britney's "baba".
He was "mad as hell I tell you" because he is nearly 5 but Britney's baby is only 2. (I think Maddox's nose was a little out of joint as he wanted to be the big brother and brag a little.)
Angelina, being the fantastic mama that she is coaxed Maddox into seating next to her in the back seat. She has now promised that she will staying at home from now on to look after him, his sisters and his new brother.
Brad, meanwhile is rushing around making sure the house is tidy (lest Angie yell's at him again) so that when mama bear arrives home with new baby bear in tow (hopefully having forgotten the "love note" issue) peace will reign on the Jolie-Pitt household. Brad has also organised for forensic scientists to get rid of any evidences of "another woman", "any other human being that may have a face" and "notes that may incriminate him".
