We all know about Brad Pitt's fondness for sustainable design, a guy named Frank and possibly Jean Nouvel, but we didn't know he was such a huge fan of that other Frank. Angelina Jolie orchestrated the ultimate gift for Pitt's big 4-3, a private tour and party at Fallingwater.

"Brad said he had wanted to experience Fallingwater ever since he took an architectural history course in college," said curator Cara Armstrong. "He and I talked quite a bit about design and art. He was incredibly well-informed about architecture."

"Brad said he had a visual sense of Fallingwater but experiencing it in person, hearing the sound of the waterfall cascading under the house and smelling the wood from the fireplace, was better than anything he could have imagined," Armstrong said.

Can't you just see this idyllic winter scene as the photo for their Christmas card?
