The Princess of Wales was left grimacing after Meghan Markle borrowed her lipgloss in an "awkward moment", according to Prince Harry.
The moment is revealed in Harry's controversial memoir Spare, which contains a string of bombshell revelations and private details about his life and family.
It has long been reported that Meghan and Kate did not share a close relationship in the early days of her royal life - despite the Sussexes along with Prince William and Kate being dubbed the 'Fab Four'.
