According to royal expert Rebecca English, when Charles turned 75 last year, Harry rang up his dad, but the fact that the conversation and details of their call hit the news was a sore spot for the king. English explained that Charles was happy to call his son this year, but is still being careful with everything between himself and Harry.

Prince Harry stepping out to meet the crowds two years after being booed at the same venue went viral on social media.

And though Harry’s “rift” with Prince William isn’t mended, the king is “hopeful” their own relations will “evolve.”
