Meghan Markle's estranged half-sister Samantha Grant, 52, is writing a tell all book revealing what it was like growing up in a bi-racial family alongside Prince Harry's love interest. Miss Grant warned that Miss Markle wouldn't like some of the book. Previously, divorcee Miss Markle, 35, was accused by her half-sister of failing to support her family. Samantha said the Queen's grandson would be 'appalled by what she's done'.


Miss Grant claimed the book would be called: 'The Diary of Princess Pushy's Sister'
