Brad Pitt and Angelina Jolie want to buy an island in Greece.

The couple, who have six children, Maddox, 13, Pax, 11, Zahara, 10, Shiloh, nine, and twins Knox and Vivienne, six, are reportedly thinking about splashing out $4.7 million on the entire island of Gaia so they can enjoy more private holidays together.

A source close to the couple said: ''Angie fell in love with it. It will need development, but at that price they'll have no problem building the vacation home of their dreams.''

The 43-acre island has secured planning permission for six villas.

The insider added to US OK! magazine: ''The kids would finally be able to run around freely without worrying about paparazzi.''

The news follows reports the pair recently put their home in New Orleans on the market for $6.5 million.

The couple acquired the property in the aftermath of Hurricane Katrina, which devastated the city, and Brad, 51, spent a lot of time there as his foundation, Make It Right, helped with the rebuilding effort.
