Tell us something we don't know. Even people who weren't remotely interested in them went through it. Anyway, Britney has revealed that her break-up from Justin Timberlake was one of the worst things that ever happened to her, saying "The most painful thing I have ever experienced was that break-up. We were together so long and I had this vision. You think you're going to spend the rest of your life together."
But it's okay now though because she's very happy with husband Kevin Federline and described him as, "The sexiest man alive. No one knows the half of what he can do. He's brilliant."
