Meghan Markle delighted fans after announcing this week that she was writing her first children's book called The Bench.

The book is based on a Father's Day poem that Markle wrote after the birth of Archie.

Meghan, Duchess of Sussex has written a children's book for @PenguinUKBooks' Random House called The Bench, about the “special bond between father and son as seen through a mother’s eyes”! More here: https://t.co/ZWcRhWj2Or pic.twitter.com/IuZkcAj4cF

However, fans on Twitter pointed out that the book is really similar to another book called The Boy on The Bench.

One person tweeted: "Almost identical to Corrinne Averiss book 'The Boy On the Bench', even the cover."

"I hope the author she ripped off is going to sue her, the cheek of this woman! The Boy on the Bench by Corrinne Averiss," another tweeted.

Averiss herself spoke out on the issue and slammed claims that the books are similar.

"Reading the description and published excerpt of the Duchess's new book, this is not the same story or the same theme as The Boy on the Bench," she tweeted.

Adding: "I don't see any similarities."

The Bench will be published by Random House Children's Books in the US and distributed in Australia, New Zealand and other countries via Penguin Random House.
