Angelina Jolie is hoping to take her six children on a month-long trek across Africa's Sahara Desert.

The 'Kung Fu Panda 2' actress - who raises Maddox, nine, Pax, seven, Zahara, six, Shiloh, five, and three-year-old twins Knox and Vivienne with partner Brad Pitt - is keen to embark on the epic trip so Ethiopian-born adopted daughter Zahara and Shiloh, who was born in Namibia, can get back to their Roots.

She told the Financial Times newspaper: "We want to cross the Sahara. It takes 28 days. It would have to be on a camel. I wonder if we could do it in pieces and station the kids along the way?

"Zahara wants to get back to Africa, and Shiloh too. So everyone takes their turns in their country."

Meanwhile, Brad and Angelina - who already own properties in Los Angeles and the South of France - are reportedly set to buy a "private and discreet" £10 million home in London's exclusive Richmond-On-Thames suburb that her 'Tourist' co-star Johnny Depp has previously stayed in.

A source told the Mail On Sunday newspaper: "It has been the best-kept secret for years for many of the Hollywood stars that if they stayed in relatively normal houses in the suburbia of Richmond, they could go around undetected.

"Johnny Depp always tries to use the house Brad and Angelina are in at the moment because it just doesn't stick out and is very private and discreet inside. Yet the house is steeped in history."
