Prince Harry said that his brother William hit him and pushed him to the floor after the Prince of Wales said that he wasabrasive.

The fight is said to be detailed in the royal's memoir, "Spare."

He tried to get William a glass of water, but he came at him.

It all happened in a blink of an eye. It's very fast. He knocked me to the floor after grabbing me by the collar. The dog's bowl cracked under my back and cut into me. I lay there for a while and told him to leave.

William said, "You don't need to tell Meg about this."

Harry wrote that his wife was sad and that she noticed the injuries.

William, the Prince of Wales and Prince Harry, Duke of Sussex, leave after attending the Grenfell Tower National Memorial Service at St Paul's Cathedral on Dec. 14, 2017, in London.
