Meghan Markle is, allegedly, jealous of her sister-in-law, Kate Middleton.

According to Globe, Markle also thinks that Middleton is uptight and insincere. Prince Harry’s wife is also, allegedly, convinced that the Duchess of Cambridge is a backbiter.

A source claimed that Markle has been jealous of Middleton since she first joined the royal family two years ago. After all, the Suits alum, allegedly, thought that she’d be the most admired and most glamorous woman in the world after marrying Prince Harry.

However, Markle’s desire to be the most popular member of the royal family immediately went down the drain amid the endless criticisms that she has received.

“Meanwhile, Kate is adored and with her model looks and figure is a fashion icon – like her hubby’s beloved late mom, Princess Diana,” the source said.

The insider also brought up an old story about Markle and Middleton reuniting at Westminster Abbey in March. They said that the sisters-in-law barely looked at each other during the outing.

And ever since Markle quit the royal family, she has, allegedly, been trashing Middleton to her friends or to anyone that listens.

“She’s become as vicious and backstabbing as her stepmother-in-law, Camilla. She’s told pals that Kate is an uptight, backbiting cold fish without a sincere bone in her body. It’s ironic because that’s exactly what people say Meghan is like,” the source said.

Before Prince Harry and Markle tied the knot in 2018, rumors swirled that the latter made Middleton cry. The sisters-in-law, allegedly, had a confrontation during Princess Charlotte’s bridesmaid dress fitting.

A source told the tabloid that Markle also tried to hurt Middleton further by refusing to make her a bridesmaid at her royal wedding. And there was also an incident wherein Markle shouted at Middleton’s staff.

“Meghan shouted at a member of Kate’s staff and Kate was horrified. Meghan is an arrogant witch who demands people to stand to attention when she clicks her fingers,” the source said.

Markle is also accused of being insecure because she’s biracial and divorced. However, her upcoming book Finding Freedom: Harry and Meghan and the Making of a Modern Royal Family will, allegedly, be her revenge.

In the book, the Duchess of Sussex will, allegedly, be able to get back at Middleton and the royal family by exposing the dirt on each one of them.
