Princess Catherine‘s sexy sister Pippa Middleton is making headlines worldwide again this week due to her newly single status.

The younger sibling has reportedly broken off her relationship to fellow Brit Alex Loudon.

The cause for the split is said to stem from Pippa’s recent ‘celebrity’ status, and that Alex simply could/would not put up with the constant media scrutiny.

A source close to Alex spoke with U.K.’s Sun newspaper saying “Pippa has become very high profile and it’s put a strain on things. They’re moving in different circles.”

It seems as though Pippa won’t stay on the market for long though. She was spotted having a romantic three hour dinner with the wealthy Duke of Northumberland‘s son George Percy last week.

The pair previously dated while they were flatmates at Edinburgh University. The Duke’s son is said to be worth an estimated £315 million.

Wow!
