Harry, 29, was attending the wedding of friends Alexander Mavros and Alexandra von Krockow at the exclusive Chateau Bela hotel where his is said to have spent the majority of the time cocktail in hand dancing among the nuptials 250 aristocratic guests.
One of the eventโs barmen told the UKโs Inquisitor that Harry was in a merry mood and was keen for the fun to continue well into the morning.
โI was about to drive off, and Harry was out in the grounds with friends. He then jumped in front of my car with his arms stretched, shouting, โArghh.โ He then told me, โDonโt go, donโt go!โ It was funny. His handprint is still on my windscreen,โ he said.
The party Prince was in such high spirits he nearly lost his phone and wallet and was very grateful when waiter, Stephen Conto gave back the items.
โWhen I returned it to the Prince he was happy and thanked me and shook my hand. I knew it was Harryโs as I had seen him with the same wallet before,โ said Conto. โHe told us that the best thing about the wedding was that he could be himself, and nobody bothered him because he was Prince Harry.โ
Harry was said to be in the company of his ex, Chelsy Davy for much of the weekend but at one point was spotted downing drinks with a mystery brunette.

Harry toured Brazil in 2012.
Today Clarence House has released the itinerary of the Princeโs tour of Brazil and Chile ahead of his arrival in Brasilia today.
The majority of the trip will be dominated by official engagements at various hospitals, schools and community projects but there will be a few opportunities to catch World Cup games which will no doubt delight sports-mad Harry.
