Sure, we all know that Brad Pitt digs architecture. From all his Architectural Digest cover to his fake-working with Frank Gehry, the guy likes dabbling in the business of building. But did you know that being an architecture buff means that you’re also crazy? So it is, according to the UK tabloid, the Sun, who has reported that the actor/hobbyist has spent roughly £50,000 designing and building a habitat for his childrens’ gerbils. This tiny playground apparently includes tunnels and platforms, all of which, according to the Sun‘s source, has helped “combine his two passions: his kids and architecture.” We can’t say one way or the other if Mr. Pitt has spent this sort of money on a gerbil house, but we think tying the two things together (“[he] pores over architectural journals like other people pore over newspapers”) is a little much, like Pitt was just giddy, screaming “Finally, I can put all of these skills to work and realize my dream of being a real architect!” (that’s right, we said screaming). Though we suppose if his buddy George Clooney spent years living with a pet pig, anything’s possible, right?
