Pippa Middleton's social schedule is generating intense speculation about who _ if anyone _ she's dating.

The young woman who wowed the world with her sensational turn as sister Kate Middleton's maid of honor is sparking speculation about whether she's still romantically linked with cricket-star-turned-banker Alex Loudon.

Instead, she's been seen around town _ and in Spain _ with former flame George Percy, son of the Duke of Northumberland, one of Britain's richest men.

The time she is spending with Percy sparked Britain's newspapers Monday to report that she and Loudon have separated since they have not been seen in public together for several weeks.

Pippa Middleton has been dubbed "her royal hotness" by the tabloids.
