Spanish King Juan Carlos' mistress gate, 2012   

74-year-old Spanish King Juan Carlos was been plagued with scandals in 2012. After apologizing to the recession-hit country for his Botswana hunting in April, Carlos quickly found himself facing yet another scandal. Spain's Vanity Fair magazine reported in May that Carlos had an affair with a 46-year-old blond German female named Ke Lina Wittgenstein, who had accompanied him on official visits and overseas journeys for on multiple occasions. The magazine claimed that Carlos had kept his illegitimate relationship with Wittgenstein for some years, and that Wittgenstein was the organizer of his hunting trip to Botswana. This is not the first time for Carlos to be involved in a sex scandal. It's an open secret that Carlols' marriage with Queen Sofia is a failure, and he has had a series of affairs over the past 50 years. Pilar Eyre, a respected author and journalist, wrote in her new book that "Queen Sofia's marriage life has been a real -tragedy. Juan Carlos is a professional seducer and age has not slowed him down."
