Chelsy Davy Puffs the Day Away in London

Back in the UK after a trip to her homeland of South Africa, Chelsy Davy was spotted over the weekend in London, England.

The blonde beauty, who has had an on/off relationship with Prince Harry, joined a few friends for lunch - proceeding to smoke and sip on wine while catching up on the latest gossip.

The sighting comes as Miss Davy's royal flame revealed plans to join injured servicemen on a North Pole expedition.

Of the endeavor, Harry said, "You will be glad to know that if my military commitments allow me I would love to join the team. I'm absolutely thrilled to become a patron of this wonderful expedition. It truly is going to be an amazing trip. This project exemplifies the tenacity and courage of those who serve our country - it really is that simple. They are a huge example to us all."
