[Egmond Codfried]

Prince Valdemar of Denmark and Prince George of Greece actually had a long-term love relationship, and were supported (also financially) in this by Princess Marie Bonaparte. She and Prince George led separate lives from early on in their marriage but slowly developed an understanding friendship and never divorced.
Marie Bonaparte was not merely ‘eccentric’ but a most interesting personality. First a client, later a college of Sigmund Freud, she played a crucial part in his escape from the Nazis from Vienna to London and became one of the female pioneers of psychoanalysis herself.
Prince Dimitri of Serbia is indeed openly gay. Reading the whole article, it's regrettable that the NY Observer indulges in sexist and bitchy comments in order to appear what they might consider entertaining.
Prince George of Kent, father of the current Duke and Prince Michael, was predominantly gay, but I guess this was mentioned here before.
