While Kate Middleton was enjoying ten days in the Seychelles Islands (just east of Africa) on her honeymoon with Prince William, her sister Pippa had fallen on such hard times with her boyfriend (professional cricket player and broker Alex Loudon) that the couple eventually just decided to break up. A friend of Pippa and Alex confirmed the split to the Times of London and said, "It is common knowledge in their close circle of friends that Pippa and Alex have recently split up." The reason for the separation is largely believed to be Pippa's new celebrity status, which conflicted with Loudon's more laid back and private demeanor.
But there's concrete evidence Pippa isn't completely devastated that her relationship with Loudon has ended. She's recently been spotted in the company of her ex-boyfriend, George Percy, who is the son of the Duke Northumberland and surely is someone who's capable of dealing with Pippa's onslaught of admirers and fans. PopEater pretty grossly suggested that she could even end up marrying Prince Harry since she's been going out and having several tea and crumpets dates with him, but hopefully that's a set of of nuptials that are pretty unlikely.
