Along with their six kids, Jolie, 36, and Pitt, 48, will call the spread home "for the next 15 months" as they make movies in the UK, the source explains. (Jolie is currently filming the Sleeping Beauty-inspired flick Maleficent at nearby Pinewood Studios; Pitt shoots Ridley Scott's The Counselor with Cameron Diaz, Penelope Cruz and Javier Bardem later this year, and Jolie has reportedly signed on for another British film after that.)
Another plus? "It's perfect because they're still close to Miraval," the source says of the even grander home they own in the south of France, where some speculate that Jolie and Pitt could hold their top-secret wedding. "They love the house!"
