Simon Cowell's dramatic weight loss was the key talking point as he made his latest public appearance in London on Monday morning.

The X Factor head judge, 60, looked slimmer than ever while greeting onlookers ahead of his appearance at Heart Radio studios in Leicester Square. 

Sporting a fitted black sweater and matching jeans, Cowell - who has lost more than 20Ibs in weight thanks to a fastidious vegan diet - was in high spirits as he made his way inside.

The music mogul added to his look with a pair of pointed Derby shoes, while trademark heavily tinted sunglasses rounded things off. 

But while it was a low-key appearance, his increasing weight loss ensured he caught the eye. 

Drawing an inevitable crowd after emerging from his car, Cowell posed for selfies with members of the public as a bodyguard waited close by.

Cowell recently admitted that he drastically changed his diet so he could keep up with young son Eric.

He told the Ellen DeGeneres Show: 'I went to see this doctor in London. We did some tests. And then a month later he said, "You have the worst diet I've ever met from any patient."

'So I went, "Okay, out of the smoking, the drinking, and diet, what do I have to drop?" And he said, "The diet." So I said, "I'm in!"

'It was easier than I thought, and part of the reason I did it was because of Eric. I realised if I didn't sort myself out physically, I wouldn't be able to catch up with him.

'Because the minute he gets up to the minute he goes to sleep ... their energy, you forget, at five years old, is phenomenal.'

Simon previously said he'd named his diet the Eric Cowell diet after his son, because the youngster loves to munch on raw vegetables.

He said: 'It's like the Eric diet because he actually, apart from ice cream, he actually likes water. I mean, who likes water? And his raw vegetables. So I'm on like, the Eric Cowell diet.'
