SEX-MAD former Spanish King Juan Carlos has a secret aristocrat daughter, a new bombshell book has claimed.
The woman, reportedly named Alejandra, has never staked her claim to the throne despite learning the identity of her dad years ago, according to the book’s authors.
Juan Carlos, 85, is said to have made sure Spain’s current king Felipe VI and Alejandra didn’t “fall in love” when they were younger as they were related.
Alejandra, who was born in the late seventies or early eighties, is said to be married with one son.
According to Spanish news website El Confidencial, she became an “open secret” in the highest circles of power.
Her existence is understood to have been confirmed by three people – an ex-lover of the former Spanish king, a long-standing businessman friend and one of her ex-boyfriends.
According to the report, she grew up in a family of “well-connected aristocrats”.
The report said: “In sixties Spain, Alejandra’s mum stood out because of her liberal and progressive profile.
“It was normal to see her in promotional and fashion events.
“Some sources claim Juan Carlos pulled strings to make sure her mother had work and a presence in the media.
“She appeared often in glossy magazines and struck up friendships with other habitual protagonists of the showbiz world, even becoming the muse of a famous haute couture designer.”
The mother was described as someone Juan Carlos met through mutual friends when they were both young.
Written by Spanish journalists Jose Maria Olmo and David Fernandez, the book King Corp, published on May 8, describes Alejandra as “tall, slim and pretty”.
They said she has “never spoken about her secret”.
Spanish royal expert Pilar Eyre briefly mentioned the former Spanish king’s aristocratic daughter in 2017.
Speaking on Spanish TV, she said: “This person has a recognised set of parents.
“Everyone in their circle of friends knows it and so does her mum of course and Juan Carlos.
“When the name comes out, everyone is going to say they look really alike.”
Eyre added: “She’s a very well-known woman from a very well-known aristocratic family and the parents know full well who the real dad of this person is.”
The bombshell claims come days after the 85-year-old former king flew to London from his Middle East bolthole.
He was pictured attending Real Madrid’s Champions League 2-0 win over Chelsea at Stamford Bridge.
He went on to spend several days in the Galician resort of Sanxenxo in only his second trip to Spain since his move to Abu Dhabi in 2020.
Juan Carlos was forced to abdicate in 2014 amid a corruption scandal.
It’s claimed the monarch has slept with 5,000 women – with his libido once labelled “a state problem” by the Spanish secret service.
At one point he reportedly had testosterone-blocking injections in a bid to quell his voracious sexual appetite.
Amadeo Martinez Ingles’ book Juan Carlos: The King of 5,000 Lovers, detailed his many affairs and painted him as a sex addict.
His lovers include Spanish singer Sara Montiel, Belgian governess Liliane Sartiau and Italian princess Maria Gabriela de Saboya.
And it’s rumoured he even tried to seduce Princess Diana, then aged 25 and married to Prince Charles, at state occasions.
Although Diana denied he had made a move, she admitted he was a “little too attentive”.
In 2015, Ingrid Sartiau claimed she was the King’s daughter, born from a fling with her Belgian governess mum Liliane, although the case was thrown out of court because of the King’s immunity.
And in January 2017 it was claimed the secret service paid former Miss World contestant Barbara Rey millions in taxpayers’ money to gag her from revealing their affair.
A Belgian housewife has claimed to be Juan Carlos’ daughter, alleging he had an affair with her mother, governess Liliane Sartiau, and a Spanish waiter Albert Sola claims he is his son.
Sola died aged 66 last year after collapsing near the Catalan city of Girona where he lived.
Meanwhile, the royal – who has been married to Queen Sofia, 84, for 60 years – has been accused of harassing his former mistress out of her £15million Shropshire mansion.
Corinna zu Wittgenstein-Sayn, whose five-year affair with the King ended in 2009, is selling Chyknell Hall after telling friends she fears for her safety from “shadowy forces” working for Juan Carlos.
The German-born businesswoman – who at 57 is 27 years his junior – has accused the King of harassing her over a “gift” of €65million, including artworks and jewellery, which he handed her in 2012 and wants access to.
She believes Spanish secret forces were behind a terrifying raid on the property in 2017.
Since 2020 she has been embroiled in a legal case against Juan Carlos after accusing him of intimidating and spying on her.
Her claims, brought to London’s High Court, will be heard at a trial set to take place later this year.
Corinna first met keen hunter Juan Carlos on a shooting weekend hosted by the Duke of Westminster in La Garganta, northern Spain in 2004.
He showered her with lavish gifts and expensive holidays and she claims the Sultan of Oman bought him a £50million townhouse near her flat in London’s Belgravia.
The king’s life has been beset by scandal, which began at 18 when he accidentally shot and killed his 14-year-old brother Alfonso.
The pair had been playing with a .22 calibre revolver owned by Alfonso when, according to royal dressmaker Josefina Carolo, Juan Carlos pointed the pistol at Alfonso.
Not realising it was loaded he pulled the trigger, shooting him in the forehead and killing him instantly.
The royal is now living in exile in a luxury hotel in the United Arab Emirates, but financial investigations are still underway and court cases from ex-lovers are ongoing.
