Pleased to be attending an event rather than planning it, Pippa Middleton** arrived at the Waitrose Summer Party held at the Natural History Museum in London on Wednesday (May 22).

The Duchess of Cambridge's sister was flying solo in a pretty peach knee-length strapless dress with matching heels as she headed inside.

Recently, the 29-year-old royal sister-in-law caught the eye of another famous Brit, though he may be a little young for her taste.

Lately, rumors are flying that Harry Styles of One Direction has Pippa near the top of the list of ladies he wants to date, though Princess Eugenie is reportedly even more appealing.
