The wedding, likely to take place in summer 2011, will surely be a lavish ceremony and perhaps similar to that amazing day when Prince Albert's mother - the American film actress Grace Kelly - married Prince Rainier III in 1956.
Regular readers of the blog will have seen these photographs before but no apologies - this is a great day in Monaco. I snapped the one of the Prince during No Finish Line last November. The smaller photo of the Prince and Charlene Wittstock was taken by Philippe Mazza during the Bain de Noel in December.
Isn't it exciting! Monte Carlo Daily Photo sends many congratulations to the happy couple. You can see the official photograph of Prince Albert and Charlene Wittstock in Monaco-Matin yesterday.
And you can read a detailed account in English, with several photos of Prince Albert and his beautiful lady by clicking on the Associated Press link.
Tomorrow - back to the boat trip!
