Ms Markle hit out at her sibling on Twitter after Meghan’s bombshell letter to her father Thomas Markle was revealed on Sunday. In the note - which was written last August - Meghan insisted that she “barely knows” her half-sister, adding that she has told “vicious lies”. Meghan wrote to her father: “I pleaded with you to stop reading the tabloids.
“On a daily basis you fixated and clicked on the lies they were writing about me, especially those manufactured by your other daughter, who I barely know.
“You watched me silently suffer at the hands of her vicious lies, I crumbled inside.”
But Ms Markle - who is penning two tell-all books about Meghan set for release later this year - took to social media to rant about her half-sister.
She wrote: “Some narcissists were “only children” , others,.., wish they were.”

Meghan’s half-sister added: “If I had 600 mill she would care.”
Ms Markle, who lives in Florida, also clashed with one of Meghan’s fans who accused her of changing her surname to “cash in”.
The 54-year-old responded: “My name has never legally been Grant so chew on that
