Felipe said in a letter that Henri was very peculiar after what he had been told, but I can't remember having read that it was known that he had male "friends". But I imagine it was of common knowledge!
I found this on Henri III:
He was his mother's favorite; she called him chers yeux ("Precious Eyes") and lavished her fondness and affection upon him for most of his life. His elder brother Charles grew to detest him, resenting Henry's greater health and activity.
His artistic tastes were a source of concern to the court. Unlike the other men of his family, he showed a marked interest in clothes and fabrics, jewels, lapdogs, and toys. He also had a keen eye for fashions and beauty which in his later years would become an obsession, and constantly appeared elegant and sophisticated, although not always appropriate – on festive occasions, he was known to dress more richly and fantastically than the ladies of the court, adorning himself with jewels and fantastic costumes, prompting the Spanish ambassador, Zuniga, to write to Philip II of Spain, "With all of this he shows who he really is". On another occasion, a ball given by Catherine de' Medici at Chenonceau in June 1577, the King whole-heartedly participated in the theme - transvestism - by wearing "diamonds, emeralds and pearls. His hair was tinted with violet powder and wearing a dress of superb brocade, he made a definite contrast to his wife", who had chosen not to dress in men's clothing.[1]
Prior to ascending the throne, he was a leader of the royal army in the French Wars of Religion against the Huguenots, and took part in the victories over them at Battle of Jarnac and Battle of Moncontour. While still Duke, he instigated the St. Bartholomew's Day Massacre, in which thousands of Huguenots were killed; his reign as King would see France in constant turmoil over religion.
On August 1, 1589, Henry III lodged with his army at Saint-Cloud, Hauts-de-Seine, prepared to attack Paris, when a young fanatical Dominican friar, Jacques Clément, carrying false papers, was granted access to deliver important documents to the King. The monk gave the King a bundle of papers and stated that he had a secret message to deliver. The King signaled for his attendants to step back for privacy, and Clément whispered in his ear while plunging a knife into his abdomen. Clément was killed on the spot by the guards

He was a man of keen intelligence and cultivated mind, and deserves as much as Francis I the title of patron of letters and art. But his incurable indolence and love of pleasure prevented him from taking any active part in affairs. Surrounded by his mignons, he scandalized the people by his effeminate manners. He dressed himself in women's clothes, made a collection of little dogs and hid in the cellars when it thundered. /www.nndb.com/people/842/000093563/
Two sources that mention Henri III...who were his favorite's? Does anyone know?
