The music boss was reportedly found unconscious by bodyguards at his London residence.

According to The Sun he was brought to hospital for a brain scan after falling down a flight of stairs.

“I’m feeling OK. I fainted. I just had a bit of concussion,” he told the paper when he returned several hours later.

Asked whether he will reappear on The X-Factor, he replied: “I will be back but I don’t know about tomorrow. But I’m feeling OK.”

The first live installment of the singing competition sees the contestants tackle the theme of ‘Express Yourself’.

It is thought that Cowell’s groups category may not perform on Saturdays show following the incident, which will see Louis Walsh’s boys perform alongside Sharon Osbourne’s girls.

The X-Factor is on tonight at 8.20pm on TV3 and ITV and 7pm on Sunday.
