Prince Harry once ‘growled at’ and slapped one of his security guards after night of drinking

The fallout from Prince Harry‘s memoir continues as readers are just now finding out about the time he ‘growled at’ and slapped one of his security guards.

The Duke of Sussex’s memoir Spare has shocked the world with its frank discussions about disagreements between family members, the prince’s sex life and his frostbitten todger.

One of the most shocking admissions from Harry involves a drunken encounter with one of his security guards.

The father-of-two tells several stories about ‘Billy the Rock’, a Scotland Yard protection officer.

The pair have a close bond and in one chapter, Harry admits to turning on Billy after getting drunk during a trip to Paris in 2007.

In a highly emotional segment, Harry describes being determined to retrace the car journey which took his mother, Princess Diana’s life in 1997.

When ‘Billy the Rock’ took him back to the hotel, the now 38-year-old prince said he tried to start a fight.

“When Billy the Rock escorted me back to the hotel, I tried to pick a fight with him. I growled at him, swung on him, slapped his head,” the Harry describes in his book.

“He barely reacted. He just frowned like an ultra-patient parent. I slapped him again. I loved him but I was determined to hurt him,” he added.

“He’d seen me like this before. Once, maybe twice. I heard him say to another bodyguard, ‘He’s a handful tonight’.”

The Prince then explains how Billy and another bodyguard ‘poured’ him into bed. When they thought he was asleep, he snuck out the hotel and walked along the Seine by himself.

Elsewhere in the book, Prince Harry shared details about his reaction to driving through the same tunnel where his mum suffered fatal injuries following a high speed crash in the Pont de l’Alma tunnel in Paris, France.

He told the driver to ‘go through the tunnel’ at precisely ’65 miles per hour’.

Billy the Rock accompanied the Prince during the trip through the tunnel and Harry said the security guard warned that ‘if the driver ever revealed to another human that we’d asked him to do this, we’d find him and there would be hell to pay’.

He described his reaction travelling through the tunnel, writing: “I leaned forward, watched the light change to a kind of water orange, watched the concrete pillars flicker past. I counted them, counted my heartbeats, and in a few seconds we emerged from the other side.”
