Pippa Middleton, Prince Harry meet for tea date
"They were alone, with no one else near to them," alleges one witness. "Everyone left them alone as this is the sort of place you can come to and escape from the rest of the world while you are inside."
Pippa has lately been rumored to be close to announcing an engagement to boyfriend Alex Loudon, though she recently spent a holiday in Spain with ex George Percy. Prince Harry, who took on-again/off-again girlfriend Chelsea Davy to the royal wedding, is reportedly single for the moment.
Will sparks fly between the royal sibs-in-law?
