"The duchASS can bow to the daddy", she wrote.
In July, Grant went on another Twitter rant in which she said Markle was ignoring her father's health concerns, adding that she would hold Markle responsible if their father died.
"I am not candy coating anything anymore!" No one wants to spoil her marriage and marriage is not at issue.
Samantha took to Twitter to post some seething tweets about Meghan accusing her of putting on "fake waves and smiles", after it was revealed that she had not spoken to her father in months.
"What is at issue is the kind treatment of our dad". "She has an obligation especially to treat our father with kindness".
Thomas has said the royals were freezing him out of his daughter's life over his alleged staged photos and controversial interview with a British talk show fronted by Piers Morgan.
It doesn't look like they'll reconcile anytime soon, because Samantha expounded on her distaste for the 37-year-old former "Suits" star with a disparaging new nickname. "I don't like the one I'm seeing now". And when I say "Meghan Markle has mailed out", I mean some poor lost soul in charge of mass mailings at Kensington Palace just spent at least a day of their life licking stamps.
However, since becoming a member of the royal family in May when she married Harry she realised that "a constant scene-stealing trait from Meghan could have alienated the public and her husband".
Meghan Markle might be literal royalty now, but she's not using that as an excuse to unlearn her good ol' fashioned manners - like saying "please" and "thank you".
