Prince Harry is getting ready to release his new book Spare next week, where he recalls a physical encounter between him and his brother, Prince William. The fight between the two brothers happened after William reportedly called Meghan “difficult, rude, and abrasive.” “It all happened so fast. So very fast. He grabbed me by the collar, ripping my necklace, and he knocked me to the floor,” he writes. “I landed on the dog’s bowl, which cracked under my back, the pieces cutting into me. I lay there for a moment, dazed, then got to my feet and told him to get out.” Harry writes that William claimed he only wanted to help his younger brother. “Are you serious? Help me? Sorry — is that what you call this? Helping me?” Harry claims that the alleged altercation left him with a visible back injury. Spare hits stores on January 10.
