Pippa Middleton 'dating heir to Duke of Northumberland'

London, Feb 3 (ANI): Following in sister Kate's footsteps, Pippa Middleton is reportedly in a serious relationship with a mega-rich Earl.

The man in question is her old flame George Percy, heir to the Duke of Northumberland.

It is one of Britain's richest and grandest dukedoms, with a vast estate that includes Alnwick Castle, movie setting for Harry Potter's wizard school - Hogwarts, the Sun reported.

Percy, 27, called Prince of the North by friends, will one day inherit the lot, including a fortune of 315 million pounds.

"George is very smitten and completely in love with her. It looks like the Middleton sisters will be completing the double before too long," a source close to the couple said.

27-year-old Pippa has been close friends with George for several years now. They met at Edinburgh University and had a fling in their final year in 2008.

Last year, they insisted that they were "just friends" after he was seen helping her get over her break-up with banker Alex Louden.

But it bloomed into love at a New Year's Eve party hosted by the Middleton family.

"Pippa sat herself next to George at supper and made sure she was hanging off his arm all night. And then she made her move," the source revealed.

"It was like a shark circling its bait. Some people think she has always set out to do this."

"Pippa has always been close to him. There is no doubt this was a huge issue for her ex-boyfriend Alex. After they parted the first thing she did was spend a weekend on George's estate in Northumberland. But now they are out in the open," the source added. (ANI)
