Princess Catherine was forced to issue a two-word warning to Prince William and Prince Harry during a tense royal engagement, according to a professional lipreader. The incident occurred just days after Queen Elizabeth II's death in September 2022, during a walkabout at Windsor Castle.
Lipreader Reveals 'Stop Arguing' Command
In an episode of Channel 5's show Lip-Reading The Royals, expert Nicola Hickling analyzed footage of the brothers, then known as the 'fab four' along with Meghan Markle and Catherine. Hickling claimed Catherine told the brothers to 'stop arguing' as tensions flared.
According to the expert, Prince William then turned to his wife and said 'Let's move.' Hickling also alleged that Meghan could feel the tension and told the pair 'Not today.'
Fractured Relationship Timeline
The relationship between William and Harry began to fracture around the time Harry started dating Meghan Markle. Prince William reportedly raised concerns about the speed of Harry's relationship ahead of the 2018 wedding, according to The Independent.
Tensions escalated further after Harry and Meghan's explosive interview with Oprah Winfrey in 2021 and the publication of Harry's book Spare in 2023, which contained damaging allegations against the Royal Family.
Harry's Hopes for Reconciliation
Despite years of estrangement, Prince Harry has expressed interest in mending ties with his brother. During a five-day visit to the UK in July 2026, Harry met privately with his father, King Charles, at Highgrove House, but did not see William.
In a BBC interview in May 2025, Harry said any reconciliation would be in his family's hands, adding: 'If they don't want that, that's entirely up to them.'
