Angelina Jolie and Brad Pitt are reportedly building a theme park for their children.
The Hollywood couple are said to have drafted plans for an underground eco-friendly playground at their chateau in the South of France, which will feature their six-strong brood's favourite rides.
The move comes after a family trip to Legoland in Windsor last September had to be cut short amid concerns about security.
A source said: "Brad and Ange felt really bad having to drag the kids home early when they were at Legoland last year. But if their bodyguards said there were too many people then they had no choice.
"Their eldest son Maddox asked if they could build something similar at the house in France. They were already getting a new pool so they decided it was a great idea."
According to The Sun, the park will be powered by sunlight using roof-top solar panels and the water will be reused.
The insider added: "There's a massive pool, slides, tunnels, boat rides, a pirate island with a castle, a go-kart track and even an old-fashioned carousel.
"Brad has designed a mini train that goes around the whole grounds and it's going to go through a door at the side of the new structure and into the park."
