On the off chance that Olivia Wilde makes you want to strangle a mountain ox, you'll probably be interested to hear her talk about her whirlwind romance and eventual divorce from Italian prince Tao Ruspoli in the new issue of Glamour. "It was the hardest thing I've ever had to do... We got engaged at Burning Man and married on a school bus. We were not conventional. I think the promise we always made was that if we are no longer happy, we won't continue. And it got to the point where I was working 10 months of the year outside of L.A. and he was doing incredible things in other places. We were no longer partners in crime," she said. "The mark of a good marriage is partnership and continuing to feel inspired by your spouse. I had that with Tao. But the end is not necessarily the tragedy. Staying in a relationship that is no longer working is the tragedy. Living unhappily—that's the tragedy." You do have a point, Olivia.
