Simon Cowell looks different after going vegan

People have noticed that Simon Cowell is looking a bit different these days.

The America's Got Talent judge has gone vegan and lost 20 pounds (approx. 9kg).

He told Access Hollywood this week that the diet change has been good for him.

"You feel better," he said. "My memory's better, I feel better, so I didn't find it difficult. I can still drink beer, so I'm happy."

The internet has noticed the change and asked about it.

What the 59-year-old has said is that he not only feels better, but he thinks he looks better.

"If I was on a one to 10 scale of being handsome, I was an eight and now I've gone to an 11," he reportedly told The Sun earlier this year.
