Dear Samantha: Please, for the love of god, just let Meghan have her moment.

Does every celebrity have an estranged half-sibling just waiting for the perfect opportunity to release their tell-all memoir?

‘Cause it kind of feels like they do.

The latest “we haven’t talked in 10 years but I’m very happy for them but also our family is deeply divided” sibling is Samantha Markle, Meghan Markle’s estranged half-sister.

Listen: Jessie Stephens thinks the royal Wedding is going to be a waste of money, and would be better spent on the homeless. Post continues after audio…

Samantha’s a mum-of-three from Florida and she’s – you guessed it – writing a memoir about her relationship with Markle. It’s called The Diary of Princess Pushy’s Sister. 

So yeah, it’s subtle… and not at all negative.

Speaking exclusively to US Weekly in the hours after the royal engagement was announced, Samantha said although she hasn’t spoken to Markle since 2008, she’s very happy for her.

Except… her impending royal wedding has created a bit of division in the family so Samantha had no choice but to write a tell-all memoir about it. Like you do.

“It created some rifts with us, but people across the pond think we’re mean people saying bad things about her, but that’s not the case,” she told US Weekly.

Samantha also pointed out that the book isn’t really about Markle. But the title, I hear you scream, the title. I know, I know.

“Everyone assumes my book is a slamming tell-all, which it is not. Now it can be egg in their faces and everyone can say what they think. My book is not a small piece and it is important historically. I wasn’t in a position to release what it was about. They assumed the worst and I think that’s unfair and our family members who spoke about my book shouldn’t be doing so.”

OK, I get it. I get that when one member of the family suddenly rises to fame the media comes sniffing. I get that it would be hard to remain silent and avoid the media. I also get that it would be very difficult to turn down a hefty book advance if it was offered to you.

But you can also say no. All of these half-siblings who come out of the woodwork at just the right time, have the choice to stay silent. To wish their estranged family member well and to leave it at that. The media would eventually lose interest.

So for the love of God, Samantha, please just let Meghan have her moment.

Please don't make this royal wedding about you and the sibling you haven't spoken to for the last 10 years. It's not about you. It's about Meghan and Harry.

Stop talking to the media and squash the book deal for your own sake as much as hers.

Because, the thing is, when the royal wedding is over and the media hype surrounding Meghan slightly dies down, you're probably going to be left with a slightly healthier bank account, but a very bitter taste in your mouth. Oh, and a forever tarnished relationship with your sister.

After all, the estranged memoir-writing half-siblings never really come out on top.
