Meghan Markle was very upset upon learning about the quarrel between her
husband Prince Harry and his brother Prince William.
Apparently, Harry confided in Meghan about the altercation and even showed her the bruises he received during the fight. The incident took place in the kitchen where William allegedly knocked Harry down, resulting in the bruises on his back.
Despite William's request to keep the matter between them, Harry eventually opened up to Meghan about it. When Meghan noticed the bruises on Harry's back, he couldn't hide the truth from her.
She was not angry, but instead, very saddened by the news. Harry's account of the incident can be found in his book 'Spare', where he writes about his wife's reaction to the news of the fight.
