We can almost always count on Prince Harry and Meghan Markle to show PDA whenever they step out, and it seems we finally know where Harry's hand-holding habit comes from: Princess Diana. Even though Harry lost his mother at the young age of 12, it's clear that Diana's affectionate side rubbed off on her son. Throughout his childhood, Harry and Diana were frequently seen hugging and being playful with each other, just like Harry is with Meghan now. In fact, remember when Harry reinvented the art of hand-holding during the couple's recent stop in Melbourne, Australia? Well, it turns out, we were wrong. It was actually Diana who taught Harry that move. Like mother, like son.
