Cressida Bonas Parties While Prince Harry Treks To The South Pole

While the prince is away it seems that Cressida Bonas will play. Prince Harry's girlfriend has been living it up while her long-term royal boyfriend braves the chill on a charity expedition to the South Pole.

The blonde was spotted enjoying a night on the tiles with half sister Isabella Branson on Saturday at Koko in Camden.

The sisters were chic in black as they hit the North London haunt to support their brother Jacobi Anstruther-Gough-Calthorpe and his DJ group Housekeeping, who were launching their latest concept, 'Seven Deadly Sin's, with an envy-themed party.

We're not sure what the royal will make of this nightclub outing. According to reports the Palace put pressure of Cressy to quit her job as a professional dancer and take up a career more suited to a future princess.

Could she be taking notes out of the Kate Middleton handbook, as wedding bells sound in the near distance?
