The crack in Prince William and Prince Harry's relationship has only deepened following the bombshell claims the Duke of Sussex made in his memoir, Spare. From commenting on his older brother's "alarming" hair loss to putting some of the blame on William and Kate Middleton for the 2005 Nazi scandal,

Prince William and Prince Harry are both fathers now, but once upon a time they were little boys growing up with one of the most famous mothers in the world. Princess Diana raised her sons with a strong sense of what it means to give back, and today, Harry and William have carried that tradition on to their children.

William and Kate shared the photo on their joint Instagram account, @princeandprincessofwales. On her own newly-launched Instagram account, Meghan, the Duchess of Sussex, shared a photo Friday of herself kissing Prince Harry along with a Valentine's Day message.
