He's one of the most well known men in the world of showbiz, but Britain's Got Talent judge Simon Cowell has stepped out looking very unrecognisable in Hollywood!
Showing off the results of his 20lb weight loss, Simon attended the America’s Got Talent quarter finals on Tuesday evening (13th August), looking slimmed down as he wore a grey jumper.
Simon made the decision to adopt a healthier lifestyle after he was rushed to hospital following a collapse at his home in 2017.
Speaking earlier this year, the music mogul admitted he's now following a vegan diet, telling 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.”
