Brad Pitt and Angelina Jolie are drawing up a $220 million pre-nuptial agreement, according to reports.

The couple - who are reportedly planning to marry next spring - are busy finalising the details of the document to ensure their four children are financially secure should they ever divorce.

A source told the National Enquirer magazine: "This secret document proves Brad and Angelina are planning to marry.

"They are very responsible parents and want to protect their children's futures, so are making sure all their assets are accounted for in this pre-nup."

The couple have an adopted Cambodian son Maddox, five, three-year-old Vietnamese son Pax Thien, two-year-old Ethiopian daughter Zahara and a one-year-old biological daughter Shiloh.

Angelina, 37, recently denied she had any plans to marry 43-year-old Brad, who she started dating in 2005.

She said: "We've both been married before. Our focus when we got together was family, and we are legally bound to our children. That really seems to be the most important thing."

The 'Tomb Raider' star has been married twice before, to British actor Jonny Lee Miller and Billy Bob Thornton.

Brad was previously wed to Jennifer Aniston.
