Nearly two decades have passed since Princess Diana passed away. But, her fame and popularity among the public persist, even across the globe.

With the current events in the lives of the British Royals, particularly with Prince William and Prince Harry, many individuals wonder what would be the dynamic between her and her sons' wives if she lives.

Cheat Sheet reported that the Princess of Wales would likely be "jealous" of Kate Middleton and Meghan Markle. A friend of hers explained the reason behind the hypothesis.

Tina Brown said that the late Princess was a "very complicated" person. Considering that she loved the two royal-born Princes "to death," this might cause a few issues between her and the two Duchesses.

The Daily Express expanded Tina Brown's statements about Princess Diana. She said that the late royal always favored Prince William more than Prince Harry.

She continued that the Princess of Wales would likely be more accepting of Kate Middleton more than Meghan Markle. She would even join the Duke of Cambridge in advising the youngest Wales Prince to take things slow with the former Suits actress.

Some reports, however, believe that Princess Diana would be happy with the Duchesses of Cambridge and Sussex. She would be happy to see Prince William and Prince Harry marrying "for love."

This comes after Tina Brown's statements that the late Princess's "biggest sadness" centered on the fact that Prince Charles did not, reportedly, love her. Her "wounded heart" became the greatest problem.

In recalling the events of her unhappy marriage, publications said that the Princess of Wales would not surely want her sons to have the same experiences with their respective marriages. She even once shared with the Duke of Cambridge that he should "hang on" to the person if he finds love, according to her revelations with BBC's Panorama in 1995.

Amid all the theories and speculations, some publications released materials showing how Kate Middleton and Meghan Markle repeatedly pay "homage" to Princess Diana. Insider listed several moments when the two Duchesses did it, emphasizing their choices of sartorial pieces and accessories were the ones that manifested it the most.

The Duchess of Cambridge named her daughter "Diana," as well. The young Princess of Cambridge's complete name is Charlotte Elizabeth Diana.

As for the Duchess of Sussex, she seemingly paid tribute to the Princess of Wales during her wedding day. She chose to utilize the "Forget Me Not" flowers, which are the late royal's favorite.
