Crown Prince Haakon’s hair-raising stunt surprised guests during a gala dinner celebrating his parents 80th birthday on 9 May.

Princess Märtha Louise and the Crown Prince (still wearing his beard) paid tribute to their parents during their speech.

Then Crown Prince Haakon disappeared during the lavish birthday banquet to have a shave and reappeared without the facial hair!

The following day, Crown Prince Haakon braved the wet weather with his wife, Crown Princess Mette-Marit, to join his parents on board the Royal Yacht Norge for a cruise and a celebratory lunch.

Before and After
