Gwyneth Paltrow worries she holds back Goop

She said: "In order to build the brand I want to build, its scalability is limited if I connect it to the band.

"So I always think how can I grow the brand, how can I separate myself from the brand and I think it's going to be more its own brand.

"More and more I would like it to be its own brand - my dream is that one day no one will remember that I had anything to do with it."

Gwyneth - who has children Apple, 12, and Moses, 10, with ex-husband Chris Martin - finds running her own business both "totally terrifying and really awesome".

Speaking at the 2016 Sage Summit in Chicago, she said: "There are so many challenges, just in terms of everything that had to learn and everything I didn't know - there was so much I didn't know I didn't know..

"The challenges I encounter every day running a business and operating a business are incredibly fulfilling, and totally terrifying and really awesome. So it's been an amazing journey."

Ventures on the site have included vaginal steaming, cupping, and surviving on a $29 food budget, and the 43-year-old actress enjoys "pushing boundaries" and causing controversy with their content.

She said: "We like to push boundaries, we like to move the needle, and we are not afraid to create some controversy once in a while."
