The Duchess of Sussex, 43, is set to star in a new Netflix programme by the end of the year.

A celebrity chef reportedly  finds being compared to Meghan Markle “insulting”, an insider has claimed.

As Meghan prepares to launch products for her new brand American Riviera Orchard, she is also waiting to launch her new cookery show on Netflix this year, which will focus on “the joys of cooking and gardening, entertaining, and friendship”.

The programme is expected to match Meghan’s new brand, which will sell a number of lifestyle products including the duchess’ very own jam produce.

However, celebrity chef Martha Stewart, 82, is reportedly finding comparisons to the Duchess of Sussex “irritating and insulting”.

Sources claimed to In Touch: “Martha has seen hundreds of Meghan types come and go — and says they all come in with the same self-inflated hype, only to find out it’s a whole new ball game when it comes down to brass tacks.

“She’s tired of being quizzed by people over how she feels about Meghan’s venture because, honestly, it’s irritating and insulting to her that she’s being compared to a rookie!

“Martha spent decades building her brand from a foundation of raw talent, hands-on hard work and an original vision.

“If Meghan thinks she can come along and replicate that with barely any experience simply because she’s married to a prince, she better think again.”

Over the last few months, the Duchess of Sussex, 43, has experienced a number of obstacles when it comes to officially launching her products, which was expected to have happened by now.

A number of these challenges have been surrounding the trademark of the brand, with Meghan being told she cannot trademark a geographical location.

As well as this, concerns have been raised about the logo, with the duchess also reportedly struggling to hire a CEO for the venture.

The official date when products will be up for sale has not yet been confirmed.

In The Mail, Royal Commentator Richard Eden said it is “a textbook example of how not to launch a business”.
