RTL News and many other Dutch news sources quote the German magazine Gala. The magazine cites 'sources close to the Greek RF' that claim that Princess Mabel is romantically involved with the French multi millionaire Arpad Busson, ex husband of super model Elle Macpherson and ex-partner of actress Uma Thurman. He also dated actress Farah Fawcett and last year the British-French actress Kirsten Scott-Thomas.
Busson is a friend of CP Pavlos of Greece. His son Flynn is dating Pss. Olympia. RTL Boulevard's Marc van der Linden claims that the Greek and Dutch RF has become even closer these last years. He claims that the members of the two RF's spend time with each other during the summer holidays since the holiday villas of the king and king Constantine are located near each other.
'Nieuwe liefde voor prinses Mabel' - RTL Nieuws
The story seems rather unlikely, considering Busson's previous taste in women. The Dutch RF is not known for their flashy acquaintances either. The last thing the Dutch RF needs is for them to be associated with a flashy twice divorced billionaire playboy who enjoys the jetset life with the top '1%' in London. The King and Queen have been critisized for years about their lifestyle which was/is deemed too flashy.
Not that that should matter if the rumours are true of course; Princess Mabel is free to do whatever she wants and I am sure many will enjoy seeing her happy again.
Since Mabel has been falsely linked to the prime minister and a Dutch-English CEO I suspect these rumours fall into the same category.
I suppose that the obvious 'source' that Gala claims to have would be the ever-blabbering society columnist Taki Theadorocopulos. He wrote about Busson and Kirsten Scott-Thomas in one of his society columns for the Spectator
last year and he is a friend of the Greek RF.
