Chris Jackson/Getty ImagesMeghan Markle's half-sister, Samantha Markle, has shared that she's releasing a second tell-all book.
Samantha, who has become known for criticizing the Duchess of Sussex over the last year, announced to her Twitter followers that her book, In the Shadows of the Duchess, has two parts.
"I couldn't help but let it slip!" Samantha wrote to her social media followers. "There are actually two books coming out! 'In the Shadows of the Duchess I and II.'''
Samantha added the hashtags #April and #June, referencing the possible release dates for the two books, the first of which is around the time of Meghan's due date.
The Duchess of Sussex is currently expecting her first child with Prince Harry.
In another tweet, Samantha referenced author Andrew Morton's book, Meghan: A Hollywood Princess, released in April 2018.
"I guess #AndrewMorton was 'fixated' when he promoted his book and he was speaking to the public," Samantha tweeted. "Everyone who has a book coming out is #fixated.. I'm promoting my book and no one has the right to stop me. Step off."
Samantha also continued to address reports that she's on police's "fixated persons list," writing, "And I'm not on a watchlist but if you want to watch something, watch my book come out."
And as for what will be in the books, Samantha has suggested that they'll include pictures of her with Meghan.
"And you will love some of the pictures in my book also to refute any of your nasty troll gossip that we did not have a life together," Samantha tweeted. "I'm very much your sister and if you don't like it too bad. Bring it on."
She concluded the tweet, "I think everyone should take a lie detector test."
