Meghan Markle, the Duchess of Sussex, has reportedly become as "vicious" and "backstabbing" as her mother-in-law, Camilla Parker Bowles. 

According to Globe, the former "Suits" star is still upset with her sister-in-law, Kate Middleton, because of how she treated her when she was still in the royal family and is also said to be jealous of the Duchess of Cambridge's popularity.

An unnamed source told Globe, "She's become as vicious and backstabbing as her stepmother-in-law, Camilla," they continued, "She's told pals that Kate is uptight, backstabbing cold fish without a sincere bone in her body."

"It's ironic because that's exactly what people say Meghan is like." 

The tipster further claimed that Meghan Markle followed in Duchess Camilla's footsteps after realizing she could never be better than Kate Middleton. 

"Meghan has been fit to be tied with jealousy of Kate from day one. She thought she'd be the most admired, glamorous woman in the world by marrying Harry," the source said.

"But instead, she turned out to be a classless TV actress."

The Duchess of Cambridge, on the other hand, is "adored and wither model good looks and figure - is a fashion icon like her hubby's beloved late mom, Prince Diana."

As per the insider, the Duchess of Sussex is said to be trying to hurt her sister-in-law on purpose - that Meghan didn't choose Kate to be her bridesmaid to upset her.

After a turbulent decade as "the most hated woman in Britain," Camilla Parker Bowles married the future king in her forbidden love for Prince Charles. 

Camilla, who was once described by Princess Diana as a "rottweiler" and the "third person" in her marriage, endured all the years in the past to get a ton of backlash for ruining Prince Charles and Lady Diana Spencer's marriage. 

But years have passed, and the public has mellowed down. They accepted Camilla Parker Bowles and even gave her affection once the British people saw how devoted she and her husband are to serving them. 

Royal biographer Penny Junor said, "She is a support to him whatever they're doing. Camilla gives him strength. He needs her. It is a very happy relationship."

The author further claims that the couple makes each other laugh and "I don't think we would have seen the man we see today had he had to give her up."

Right now, Meghan Markle is one of the most hated persons in Britain because she took away their prince. 

She had no choice but to escape intense public backlash after her every move and the cold reception she has also received inside the royal family. 

But the difference between Meghan Markle and Camilla Parker Bowles is that the Duchess of Sussex hated the UK and didn't like the restrictions of the royal life. 

"Meghan didn't like the UK. It was too small for her. She hated restrictions that she couldn't do exactly what she wanted when she wanted," said Angela Levin. 

On the other hand, Camilla Parker Bowles knows that her husband is the future king of England. And whether she likes it or not, out of love, she stood by his side and would also help him out.
