There had been high hopes for the Princess of Wales and Meghan Markle to hit it off and become a force to be reckoned with.

But it seems the two strong women never really saw eye to eye after Prince Harry first started dating Meghan – and tension between the pair started simmering almost straight away. One rather awkward standoff between the pair came before Harry and Meghan’s wedding when the couple, along with Prince William and Kate, had been dubbed the ‘Fab Four’.

During an outing in February 2018, the royals took part in a Royal Foundation Forum, where they were quizzed about their charity work and brothers William and Harry joked about having disagreements. And in his memoir Spare, Harry recalls that backstage before the forum, there had been a tense moment between Meghan and Kate – and it was over lipgloss.

He explains how Meghan asked to borrow Kate’s lipgloss, which left the Princess of Wales grimacing. He writes: “Meg asked to borrow Kate’s lipgloss. An American thing. Meg forgot hers, worried she needed some, and turned to Kate for help. Kate, taken aback, went into her handbag and reluctantly pulled out a small tube. Meg squeezed some onto her finger and applied it to her lips. Kate grimaced. Small clash of styles maybe.”

The detail about the moment is one of many in Harry’s book that sheds new light on what really happened between Kate and Meghan during the latter’s time as a working royal. He also alleges that Meghan upset Kate by saying she must have “baby brain” in the run-up to the Duke and Duchess of Sussex’s 2018 wedding when she was pregnant with Prince Louis.
