Latest news:Meghan: I’m an over-achiever because my blood is type A:see more

The Duchess of Sussex joked that she is an over-achiever because her blood type is A positive.

She interviewed her “close friend” Jamie Kern Lima, just hours after she appeared on the make up entrepreneur’s own podcast, during which it emerged she was still using her HRH title in a personal capacity.

An image of the basket of ice cream and home-made strawberry sauce sent by the Duchess to Ms Kern Lima showed a monogrammed card adorned with the printed message: “With Compliments of HRH The Duchess of Sussex.”

Both the Duke and Duchess of Sussex agreed to stop using their HRH styles when they stepped down as senior working royals in 2020, but a source close to the couple insisted that was only for commercial purposes and that they did not use them publicly.

The Duchess told Ms Kern Lima, who in 2016 sold her business to L’Oreal for $1.2 billion (£900 million): “I feel like we haven’t talked about our blood type, but yours is probably an A positive like mine, because I was like ‘Even my blood is over-achieving’.”

In the fourth episode of her podcast, Confessions Of A Female Founder, she revealed that Oprah Winfrey had advised her to channel her own “essence” when she was setting up her business, As Ever.

The Duchess recalled: “She was the one that said, ‘There are tons of things you can put your name on, but for you and how you like to show up for people, once you figure out how to encapsulate your essence, then you’ll know.’

“It was so clear… the essence of who you are was about feeling seen, knowing that you’re enough, knowing that you’re beautiful, despite what anybody would say, and putting that essence in a product that could be shared with millions of people.”

Fear of failure

The Duchess described how she started small with her jam-making business venture, because of a fear of failure.

“At the beginning, I just liked making jam,” she said. “All I liked to do was just make jam and preserves. And it went from ‘OK, I’m going to share this jam with lots of friends and family’, to ‘People really like it and it brings me joy, so maybe I can share it more broadly’.
