Pippa Middleton dating George Percy, 'Earl of Hogwarts'?

pippa-middleton-george-percy-gi.jpg Pippa Middleton, royal sister-in-law and one of the most eligible bachelorettes in the U.K., is off the market, according to reports.

The Sun newspaper reports that Middleton is dating old college flame George Percy, heir to the Duke of Northumberland. Percy is also known as the "Earl of Hogwarts" because his ancestral home, Alnwick Castle (below), was apparently used as for exterior shots of "Hogwarts" in the "Harry Potter" movies.

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

The couple's romance, according to the source, blossomed at a New Year's Eve party.

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