Samantha Markle, 53, claimed yoga instructor Doria Ragland was "probably sitting there crying" during the romantic ceremony, saying the 61-year-old had "sold out".
The American even compared the royals to the Addams Family as she continued to lambaste her new in-laws days after Meghan tied the knot with Prince Harry.
In her most recent Twitter rant, Samantha claimed she had never said Doria had "hogged the limelight", instead saying: "She looked more like the hockey player in the penalty box."
She added: "She was probably sitting there crying because she knew that she sold out in cashed in bigger than anyone, and that she isolated our dad. Guilty."
The American, who has often defended her right to "free speech", also shared a satirical piece about the royals, saying: "they are like the 'Addams family' but with billions of dollars".
Doria captured the heart of the nation as she was overcome with emotion while watching her daughter marry Prince Harry in the romantic service at St George's chapel.
The proud mum struggled to hold back tears as she sat alongside the Royal Family for Saturday's ceremony.
The 61-year-old has also appeared to have been embraced by her new family, reportedly striking up a friendship with Prince Harry and being welcomed into the family by Prince Charles.
She had flown into the UK just days before the big day to be by Meghan's side after plans for the wedding were thrown into chaos due to Thomas Markle changing his mind several times over whether he would attend.
Since the pair got married, Samantha has appeared to grow more resentful over the wedding, which she was not invited to.
But she tried to appear indifferent to not being invited, saying on Twitter: "I was not miserable. It was quite comfortable. London would have been too much of a madhouse and I don’t like crowds."
She also suggested the most appropriate attire for the wedding "would have been a dress made out of tabloids of a hazmat suit".
