The world's most famous couple are said to have been in talks with lawyers to agree a $366 million split deal.

Legal papers, which the pair allegedly signed this week, reveal they plan to divide their fortune and share custody of their six kids.

Though Brad and Angelina are not married, British newspaper 'The News of The World' claims the megastars have secretly signed legal papers that detail how all their homes and assets will be carved up.

The agreement gives them joint custody of the kids but all six will actually live full-time with Angelina.

Preparations for their break-up reportedly began in December when they visited a Los Angeles legal firm to begin thrashing out a deal.

An announcement of their separation is expected to be made soon, ending months of speculation that the five-year relationship is on the rocks.
