More details have come to light regarding the beginning of Prince Harry and Meghan Markle’s whirlwind romance along with the royal’s private Instagram handle,

From the latest extract of Finding Freedom – a new book about the couple's exit from the royal family, a Daily Mail insider told the tabloid that the biography is sure to have “torpedoed” any chance at re-entry into the royal family after the one-year review period of “Megxit” is over.

The latest Finding Freedom extract published in The Times on Monday reveals how the couple had their first date in a private room at Dean St Townhouse in Soho, London.

The pair had one trusted waiter to attend to them and reportedly used a secret entrance to enter and exit the building in order to keep their relationship private.

The source went on to mention that not too long after the couple’s date, she “began to follow a mysterious-looking Instagram account by the name of @SpikeyMau5.”

“With no face visible in the profile photo, just a mouse-shaped helmet, it would have meant nothing to most people. But it was in fact Harry's private account,” the authors of the book wrote.

“A big house music fan, he crafted the pseudonym by using part of the name of one of his favourite DJs, Deadmau5.

“Spikey came from a Facebook alias that Harry used for an account he had under the name of Spike Wells.

“’Spike’ was a nickname sometimes used for the prince, particularly by Scotland Yard officers. Harry's Facebook account (before he shut it down) had a profile photo of three guys in Panama hats taken from the back in an MGM Grand Las Vegas hotel suite.

“The account said he was from Maun, Botswana. Prior to that photo, Harry used the image of King Julien, the eccentric lemur from the Dreamworks movie Madagascar.”

The book extract also claims that the couple moved on to a serious relationship very quickly and the Prince would regularly visit her in Canada.

He reportedly would be seen flying commercially with just one security guard.

“It didn't take long for Harry's visits to become an open secret among the residents. As one of Meghan's neighbours said, ‘When a black SUV was parked with guys inside wearing headsets and eating burritos, we'd say, 'Hey, Harry's in town!,” the extract read.

“But the news never went further than the community Facebook page, typically devoted to discussions about shovelling snow and dog poop.”

Book authors, journalists Omid Scobie and Carolyn Durand reportedly had access to more than 100 people for the book.

The couple issued a statement saying they have not collaborated or given an interview for the book.
