Weekend at Mum and Dad's!

Pippa Middleton left London on Friday with beau Alex Loudon -- bound for Bucklebury, her family's home in the countryside.

An insider tells Us Weekly that Middleton, 27, spent her Friday afternoon in a short business meeting followed by a visit to a coffee shop, garden center and a local pub with a pal. Loudon, 30, picked her up in his car in the early evening, and the couple arrived at the house where her parents Michael and Carole Middleton still live.

Middleton and Loudon have been dating for about a year. Loudon stayed behind in London for her international excursion to Spain with pals two weekends ago.

Like most of Middleton's beaus, Loudon comes from posh stock: The son of a retired financier, he attended prestigious schools Eton and the London Business School and is a descendant of an earl, with links to the Dutch monarchy.

Might England's most talked-about bachelorette walk down the aisle soon, like her famous sister Duchess Kate?

"Soon it will be Pippa's time to shine," one source recently teased to Us Weekly.
