Soon-to-be-royal Meghan Markle has been looking outrageously loved-up with her fiancé Prince Harry – but apparently not everyone adores the roguish redhead as much as Markle (and tbh, the rest of us).

Markle’s half-sister Samantha Grant, who has made a hobby out of running her mouth about her sibling since she started dating Harry, has slammed the Prince over a comment he made about Markle’s family.

While guest-editing BBC Radio 4’s Today programme, Harry talked about how much he enjoyed spending Christmas with his brother Prince William, sister-in-law Kate and his new fiancée.

The family loved having her there. We had great fun staying with my brother and sister-in-law and running round with the kids. Christmas was fantastic. She’s done an absolutely amazing job, she’s getting there and it’s the family that, I suppose, she’s never had.

Well, Grant did not take kindly to that little dig at all, and fired back via Twitter saying her 36-year-old sister was simply “too busy” to dedicate time to her large family.

Grant, who has the same father as Markle, is 17 years older. She has been outspoken about her “social climber” sister in the past, and has revealed her plans to release a tell-all book called The Diary of Princess Pushy’s Sister.

If she keeps this up, it looks highly doubtful that the outspoken Grant will score an invite to the most hotly-anticipated wedding of 2018.

Maybe she can just, er, send a card instead.
