Meghan Markle and Prince William allegedly had a row after she made a comment about Kate's hormones when her sister-in-law was pregnant with Prince Louis, Prince Harry claims.
In a leaked extract of his tell-all memoir Spare, which will be published in the UK next week, the Duke of Sussex claims that in the run-up to his wedding in 2018, Meghan told the Princess of Wales that she must have "baby brain".
The remark went down like a lead balloon and in a bid to move past the incident, the couples met up - but this led to a row between William and Meghan, the book claims, where he apparently said she was 'rude'.
