On Sunday, Cowell tweeted: "Some good advice ... If you buy an electric trail bike, read the manual before you ride it for the first time. I have broken part of my back. Thank you to everyone for your kind messages."

In a follow-up tweet, Cowell added: "And a massive thank you to all the nurses and doctors. Some of the nicest people I have ever met. Stay safe everyone. Simon."

According to People's source, Cowell underwent a five-hour surgery on his back, which was broken in multiple places: "He has had to have a number of fusions and metal rod put into his back," the source said.
