Meghan Markle's Mask Slips: 'Narcissistic' Duchess Exposed as 'Menace' Amid 'Not Surprising' Bullying Allegations After Oprah Winfrey Bombshell

Meghan Markle displayed "narcissism" as far back as her and Prince Harry's March 2021 interview with Oprah Winfrey. But Her one-time Royal Highness's biggest display of selfish behavior was reportedly when she spent 22 months as a "barely" working British royal from 2018 to 2020.

A former palace courtier told an outlet "there definitely were bad, very bad, even psycho moments," before adding, "I witnessed people being chewed up in person and over the phone and made to feel like s---."

"It was an incredibly fraught time and I'm inclined to give her the benefit of the doubt," the anonymous ex-royal aide continued. "She has said herself she was suicidal at times."

In response to these new allegations, historian Hugo Vickers shared, "Well I'm afraid I'm not surprised by these allegations because even when she was at Windsor I remember hearing from very good sources that there was trouble. There was a time when she was very rude to one of the undergardeners at Windsor when they were at Frogmore Cottage. The head gardener went to complain to the Queen and she told her off because she obviously didn't like people being rude to staff."

He further added, "None of these other stories surprised me. She probably is not very good with staff or people that she's employing. It's just very unattractive."

Upon their marriage in May 2018, and long before "Duchess Difficult" was exposed, Harry and Meghan became the Duke and Duchess of Sussex — and "one of the most difficult of senior royal couples in modern royal history," according to another palace insider.

"There were staff in the royal household complaining about the way Harry and Meghan were treating them," royal expert Richard Palmer told an outlet. "I've certainly spoken to people who have said that nothing they did for them was ever right – and there was always a massive inquest after every royal engagement that they did."

He added: "It would be: 'Why did we do this? Why did you say that?' I think it was really difficult for a lot of people."

Once they eloped, Harry and Meghan were both granted full and free, 24/7 protection from Scotland Yard, and their own official office and residence within Kensington Palace, complete with their own Sussex cipher.

This led Vickers to observe, "She is lovely when it is all going her way but a demon when the worm turns. I think quite a lot of actresses have a narcissistic side to them."

He concluded, "Of course, it can be very stressful leading up to a wedding. But once again this is when your true character comes out. We can all be very polite when things are going well. It's when we're under stress that you see people getting annoyed and aggressive."
