Simon has lost over 20 pounds thanks to a demanding vegan diet, which he changed to keep up with his son.
In August, Simon was taken to hospital for six hours of surgery after breaking his back in an electric bicycle accident at his home in Malibu, forcing him to cancel all his television job scheduled for the rest of the year.
The X Factor judge had stayed in Los Angeles while recovering from his accident, but last month he was seen happy and healthy in Barbados for a family trip.

The crash occurred when the powerful machine “flew in the air and made an accidental wheel” after trying to change gears.
The music chief is believed to have been “surprised by the power” of the bike and knew immediately that he “had problems”.
After the accident, Simon tweeted, “Some good advice … If you buy an electric trail bike, read the manual before riding it for the first time.”
He continued: “I have broken a part of my back. Thank you all for your kind messages.
He then added in a second tweet: “And a massive thank you to all the nurses and doctors. Some of the friendliest people I’ve ever met. Rest assured, everyone, Simon.

His recent injuries and continued recovery brought him out of Britain’s Got Talent series played in 2020 after he returned after England’s first closing.
In 2019, Simon said about his healthier lifestyle on The Ellen DeGeneres Show: “I went to see this doctor in London. We did some testing. And a month later, he said, “You have the worst diet I’ve ever known from any patient.”
Simon added: “It’s like Eric’s diet, because actually, apart from ice cream, he likes water. I mean, who likes water? And his raw vegetables. So I follow his diet. Eric Cowell.
The TV judge’s new physique has impressed his famous friends, as his close friend and British youth partner Got Talent, David Walliams, joked that the star has become a “skinny”.

Amanda Holden, who is also a member of the group with Simon for Britain’s Got Talent, also spoke about her weight loss and claimed it was the result of Simon switching to “skinny lager”.
Speaking to Good Morning Britain to welcome Piers Morgan, he said: “Drink light beers, that’s the secret.
“And I tasted it because I thought I was going to try it, like, naff. It’s actually pretty decent. You could give it some advice!
Meanwhile, Simon also talked about reducing alcohol last year, told Extra, “I went to see this well-known guy. And he told me, after doing some blood work, ‘You can’t having red meat, dairy, sugar, bread and gluten. “
I’m thinking, “What about alcohol?” And he said, “Maybe not as much as before.” And I did, I stayed and it’s easy.
Eric is Simon’s only child and has credited his son with having changed his life for the better since he was born in 2014.
Speaking to ITV’s Lorraine in September 2019, Simon explained the impact Eric had on him and said, “Now I see my life through his eyes and it’s so much simpler and it’s so much more fun.
“When you’re a father, something clicks on you. It’s about them … It becomes very protective and, above all, it’s part of the reason I’ve changed everything in my life.
