Simon Cowell is to invest £500,000 in a low-calorie alcohol company

And Simon has become such an "absolute devotee" to the drinks - which have just 89 calories per bottle - he's decided to invest in the company as he's sure other people will be just as impressed.

A source told The Sun newspaper's Bizarre column: “Simon is an absolute devotee to Skinny Beers and he has decided to buy into it. He drinks two of them a night and after some thought knew he wanted to get involved.

“The drinks are all vegan, gluten-free and kosher so it ticks all of the boxes when it comes to Simon’s dietary requirements.

“He gave up meat and dairy as part of his fitness kick and having this alcoholic drink instead of another means he’s not breaking away from his routine.

“Simon is now planning on investing £500,000 in the company and believes Skinny Lager can become a mainstream drink in the UK. He is so confident about the product and now wants to put his name to it.”

The 61-year-old star overhauled his lifestyle after breaking his back last year and now has regular sleeping and exercise habits.

As well as walking 40 miles a week, the 'X Factor' boss rearranged his work schedule to ensure he only starts business meetings after 9am rather than hold conferences into the early hours of the morning like he used to.

A source previously said: "Simon said how he hasn't worn trainers as much as this in 20 years. He feels fitter than ever before and is keeping to a normal routine rather than being on the phone until into the early hours of the morning."
