"She's done an absolutely amazing job," he said of his fiancé while guest editing the BBC's radio program, Today. "She's getting in there and it's the family, I suppose, she's never had."
Samantha Grant took to Twitter to respond, claiming that it was Meghan who shunned her own large family.
“Actually she [Meghan] has a large family who were always there with her and for her.
“Our household was very normal and when dad and Doria divorced, we all made it so it was like she had two houses.
“No one was estranged, she was just too busy.
“Meg’s family (our family) is complete with sister, brother, aunts, uncles, cousins, and the glue of our family, our amazing completely self-sacrificing father. She always had this family ... Marrying merely extends it.
“She has a large family. She always did. Our dad is amazing and completely self sacrificing. We made it so that she had two houses. How fun it was!”
Grant has previously labelled her half-sister a "shallow social climber" claiming she's shunned her family since landing a role on Suits. She's also planning to write a tell-all book called The Diary of Princess Pushy’s Sister.
