Pictures of Angelina Jolie Playing With Twins Knox and Vivienne Jolie-Pitt in Glasgow, Scotland

Angelina Jolie spent yesterday afternoon playing at the Carnell Estate in Ayrshire, about 40 minutes from Glasgow, with her kids Knox and Vivienne. The Jolie-Pitts are together in Scotland at the moment as Brad continues working on World War Z in Glasgow's city centre, which has been made over to look like Philadelphia. Brad and Angelina are renting Carnell House, a 16th-century mansion set on 10 acres of well-manicured grounds. The estate contains a variety of properties than can be rented for long-term stays, and it seems Angelina and Brad have chosen to plant roots there temporarily after a stay in the London neighborhood of Richmond earlier in the month. While Brad's busy with his zombie flick, he's still looking forward to his next endeavors. Brad will produce Twelve Years a Slave, a film based the 1853 autobiography from free-man-turned-slave Solomon Northup.
