Pippa Middleton & Alex Loudon: Private Nightclub Partiers

Blowing off steam following a long day's work, Pippa Middleton partook in a fun-filled night on the town with her man in London, England on Thursday (August 25).

Partying it up til the wee hours of the mornings, the sister of Duchess Kate was alongside her investment banker beau Alex Loudon as the pair hit up trendy Public Nightclub & Bar on Kings Road.

After a few hours of drinking and dancing, the cute couple shuffled out to a taxi while responsibly grabbing passenger seats for the ride back home.

According to recent reports, Miss Middleton is said to have moved her belongings into Loudon's pad for what's being dubbed as a "trail" marriage.

A source told UK tabloids of the test run, “They’re experimenting with a ‘trial marriage’ to find out how they cope with living together. So far, so good.”
