Simon’s new ventures and lifestyle changes come after the star took on a new commitment to healthy living and achieved a 20lb weight loss as a result of going on an animal product-free diet.

His practically vegan diet involves cutting out meat, dairy, sugar and gluten.

The star was inspired to change his lifestyle after he was hospitalised in October 2017 after fainting while going down the stairs as a result of low blood pressure.

Speaking last month about his new diet, Simon explained he discovered he was intolerant to red meat, dairy, sugar, bread and gluten.

He told Extra: ‘I went to see this guy who’s very well-known. And he said to me, after doing some blood work, “You can’t have red meat, dairy, sugar, bread or gluten”.’

But the X Factor boss added that his first thought following the advice was ‘What about alcohol?’

Simon said: ‘And he said, “Maybe not quite as much as you had before”. And I did it and I stuck to it and it’s easy.’

Simon now lives a happy and healthier life with his partner Lauren and their five-year-old son Eric.
