Britney haunted by Timberlake split

Britney Spears has revealed that her break-up from Justin Timberlake was her most painful experience.

Although now happily married to Kevin Federline, Britney told The Scoop: "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."

She went on to sing Federline's praises, describing him as, "The sexiest man alive. No one knows the half of what he can do. He's brilliant."
