P-Middy, the Brits call her. That's Pippa Middleton, 28, sister-in-law to the royals and princess of the paparazzi, who stalk her so often they caught her coming out of her old boyfriend's home at 7 a.m. last week.

A British tabloid called The People spotted her loading her bags into the trunk of her BMW Z4 convertible outside the home of her ex-lover, cricket-player-turned banker Alex Loudon, who left about an hour later on a scooter wearing a white helmet. The tab printed its story, along with several snaps, over the weekend and The Daily Beast's royals correspondent passed on the news today.

"P-Middy is off the market," Tom Sykes' column began.

Loudon was supposed to be P-Middy's great love, but he split up with her last year because, according to London media reports, he didn't like her new sex-symbol status nor the media attention after sister Kate Middleton married Prince William last year. The fact that the paparazzi are tracking where she spends her nights suggests why he might have been fed up, to say nothing of how she feels.

"It's Back On!" shouted the headline in The People, which cited a "family source" confirming the two are back together again. The next day, tennis fan Pippa turned up at Wimbledon with brother James; last year, she was there with Loudon.
