Angelina Jolie has revealed that partner Brad Pitt is keen for the couple to hire a live-in nanny to help them raise their expanding brood.

The couple already have four children - adopted kids Maddox, six, Pax, four, Zahara, three, and biological daughter, Shiloh, two - and Angelina is expected to give birth to twins with weeks.

With the prospect of six children to look after, combined with their movie schedules, Angelina has reluctantly conceded that they could probably do with the extra help.

"With two little babies to look after, I guess you reach a point where it becomes a practical question and we'll need full-time help," she admitted.

Despite this, it seems that Brad is the main driving force behind the decision because he fears his wife is taking on too much.

"He's only worried when I don't get enough rest, or when he sees me picking up Maddox or Pax. My doctor says I'm not supposed to be doing that," explains Angelina.

Angelina also gives an insight in the day-to-day reality of life chez Brangelina.

"We spend a half hour or so with Maddox before going to sleep. Being the eldest, he gets to stay up a bit later. I spend more time with Shiloh in the morning, because she wakes up first. And Brad will take care of our other children while I'm with her. So there isn't any debate or conflict going on because of our kids," she tells Closer.
