Historian Tessa Dunlop believes their upbringings played a major role in this divergence.
Meghan's Hollywood background, and the cutthroat competition that comes with it, contrasts with Kate's more deferential upbringing.
Meghan's values are completely inverted from Kate's, making it more difficult for her to fit into the royal family.
Dunlop suggests that Kate's decades-long training prepared her well for life in the royal family.
Despite hopes that Kate and Meghan would be friends, there have been well-documented disagreements between the two women.
These disagreements make it unlikely that Kate and Meghan are on speaking terms.
