She suggested this sense of competition could have translated into jealousy. Louella suggested: “Seeing Harry’s close relationship with Kate could have triggered feelings of envy and insecurity for Meghan, making her feel like she had to compete for his attention and affection.”

Louella added: “Constant competition and comparison with someone, especially when they are close family, can create a toxic dynamic and make it difficult for two people to have a genuine connection. It’s possible that Meghan’s jealousy towards Kate could have contributed to any deeper issues between the two sisters-in-law.

“In the end, it’s important to remember that both women are human and may have their own insecurities and vulnerabilities, which could have affected their relationship. There are likely many nuances and complexities to Kate and Meghan’s relationship that we may never fully understand, but it wouldn’t be surprising if jealousy played a role in their dynamic.”

Her comments come after Ingrid Seward told The Telegraph: “I think that Meghan must have been incredibly envious and then jealous of Kate. I heard Meghan actually thought she was going to be a princess and live in Windsor Castle. Instead, there’s William and Kate with this beautiful house, while they are stuck in Nottingham Cottage.”
