Last month, Simon made his health a top priority after a fall left him hospital bound and unable to attend X Factor live shows.
The music mogul had been going to get a cup of milk to help him sleep when he fell - leading him to be stretchered out of his home in a neck brace.
'I'm alright. In a weird way it was a wake up call because it wasn't the end of the world. It was a bit embarrassing...' he said on ITV's Lorraine at the time. 'I feel much better this year, I'm not having so many meetings or late night calls, it's a bit more of a balance.'
Simon shares four-year-old son Eric with girlfriend Lauren Silverman.
