It’s a known fact that Brad Pitt is extremely passionate about anything that involves his kids. The latest news just proves it once more that he is a doting father. The hunk has splurged 50,000 pounds ($82,740) to customize a run for his children’s Gerbils. The 45-year-old star personally oversaw the whole venture at his family’s French estate. The run has a web of tunnels, seesaws, and platforms that make it the most luxurious home for rodents.

“Brad pores over architectural journals like other people pore over newspapers. He had so much fun putting the run together with his kids Maddox, Zahara, Shiloh and Pax,” the Sun quoted a source as saying. “It’s incredibly complex and cost a lot but Brad’s more than happy with any activity that can combine his two passions – his kids and architecture,” the source added. The star has always had a penchant for architecture, and even had an informal apprenticeship with Frank Gehry, the renowned architect, in 2005.
