Simon Cowell has opened up about his recent body transformation, revealing he has lost an impressive four stone in a year.
The music mogul has been looking trimmer and trimmer in recent months, and has revealed his secret to shedding the excess weight is sticking to a routine - and avoiding takeaway pizza.
Talking with pal and former girlfriend Terri Seymour on US entertainment show Extra, the X Factor judge revealed how he managed to lose weight.
He revealed: "I think I have dropped, since I started this diet a year ago, 60 pounds. I'm doing a bit of cooking. I'm exercising.
"Funny enough, more during this time as well, sticking to the diet. The only difficult thing is when Eric orders a pizza. That's the number one thing I miss."

The 60-year-old went on to advise the most important thing to do is stay occupied and stick to a routine.
He added: "Most importantly, occupy your mind. You have to stick to a routine. Fortunately, with things like Zoom, you stay in touch with the world, keep motivated, come up with ideas... I never get this time, normally."
Cowell previously told the show he was watching his weight by cutting down on alcohol and removing bread, sugar and red meat from his diet.
He told The Sun recently: "All I do is avoid just red meat - white meat is fine - and I eat loads of vegetables, salads and drink this great beer.
"If you're on a diet you have to keep the food sensible, but it's got to be interesting and tasty, then the diet's surprisingly easy.
"I'm on a diet but it doesn't feel like it now because the food I eat is really healthy and I don't find it tedious. If it's boring you won't stick to it."
