PIPPA Middleton seems to be staking her claim as the world's most eligible bachelorette, after dumping boyfriend Alex Loudon.

Kate Middelton's little sister became a one-woman phenomenon after her pert bottom received as much world attention as the the royal marriage of her big sister to Prince William last month.

And pals say her derriere's massive global fame has placed strains on the relationship.

But don't get over-excited guys – the Duchess of Cambridge's sexy younger sister has been chummying up to her mega-rich ex-boyfriend George Percy, and the pair dined together at  Le Cercle restaurant off London's Sloane Square last week

One source revealed: "Pippa has become very high profile, thanks largely to the attention her bottom received in that bridesmaid's dress.

“It's put a strain on things. Her and Alex are moving in different circles."

Pippa and George were also spotted together at Queen's tennis club in West London watching Andy Murray play.

George is son of the Duke of Northumberland and heir to his dad's £315million fortune. Pippa Middelton and George Percy dated when they were flatmates at Edinburgh University.
