Pippa Middleton's Brother Parties With Prince Harry

Pippa Middleton keeps warm in a cropped leather jacket while heading to work on Thursday (December 22) in London, England.

The day before, the 28-year-old younger sis of the Duchess of Cambridge wore a chic trench coat and gloves for the chilly winter weather.

Later in the evening, Pippa‘s brother, James, reportedly partied with Prince Harry and David Beckham at London’s Arts Club, where the royal was spotted wearing a festive Santa hat inside.
