Brad Pitt and Angeline Jolie are reportedly planning to sign a £200 million pre-nuptial agreement.

They are said to have negotiated a 101-page document that states that, even if they split, he will keep his £110m fortune, while she will keep her £90m assets.

Considering they have both been married before, it stands to reason they are being very careful this time around.

The couple have six children and own a number of properties around the world.

A source revealed to Grazia: "Angelina has always been a bit reluctant about having a pre-nup but Brad persuaded her it's for the best.

"He's a romantic guy, but also very practical, and given they're worth £200 million between them, with six children and a lot of property across the globe, it definitely makes sense.

"Both Brad and Angelina have been married before so they know how messy a divorce can get.

“It's even more important this time because there are children involved and Brad wants them to cover all eventualities."

Angelina split from Billy Bob Thornton in 2003 and Brad divorced Jennifer Aniston in 2005.

Angelina with her mother Marcheline

The couple are thought to be organising a ceremony in Hawaii which was the favourite place of Marcheline Bertrand, Angelina’s late mother.

A source told the magazine: "Hawaii means that her mother can be a part of a small ceremony on her favourite beach. 

“Then the main event will be a wintery-themed bash in France with all of their closest friends and family. Everyone, especially the children, is very excited.

"They love the idea of a Christmas wedding at their French home, Chateau Miraval, with a big roaring fire and lots of festive decorations."
