Meghan Markle’s half-sister is writing a book revealing what it was really like to grow up with the actress.

In a series of tweets, Samantha Grant announced the working title of the tell-all memoir is The Diary of Princess Pushy’s Sister and stated that Meghan “won’t like some of it.”

Meghan, who has been dating Prince Harry since last summer, is being accused of failing to support her family since gaining fame.

Her estranged half-sister is wheelchair-bound due to suffering from multiple sclerosis and has slammed Meghan for having no “basic human consideration.”

Although the actress is known for her charity work, Samantha believes that “talk is cheap” and Meghan could donate some of her own money to people in need.

“People who are starving and too poor to afford sanitary napkins don’t need a voice. They need money and donations,” she tweeted.

After being accused of cashing in on her royal connection, Samantha challenged people to “take any money that the public thinks I want and give it to starving people in Africa or India.”

She also said that the royal family would be “appalled” by Meghan’s treatment of her own family, adding: “The truth would kill her relationship with Prince Harry.”

It was recently revealed that Meghan is set to take her relationship to the next step by moving into a brand new apartment in Kensington Palace with her royal beau.

There has been no word from Meghan’s camp on Samantha Grant’s upcoming book.
