WATCH: The clip that proves Kate and Meghan's feud is a lie
Rumours of a royal rift started months ago with claims that the former Suits star made Kate cry at a fitting for Princess Charlotte’s bridesmaids dress.
Speculation of a feud mounted when Kate was notably absent from Meghan's lavish New York baby shower earlier this month, skipping the festivities in favour of a family holiday with Prince William and their three children at an upscale French ski resort.
Kate and Meghan's last public appearance together was on December 25 when they attended Christmas Day service at the Church of St Mary Magdalene Her Majesty's Sandringham estate with their spouses Prince William and Prince Harry.
According to royal commentator and former Sunday Express editor Martin Townsend, the rumours that Kate Middleton and Meghan Markle are feuding are really just a clever ploy to distract the public from the real feud - between their husbands, Express.co.uk reports.
