Speaking as the new series of BGT goes head to head with The Voice on Saturday nights, Simon insisted he's only interested in watching one of the coaches on rival series.
"Now Jessie I would snap up," he told the Daily Mail, while again insisting he had never offered Sir Tom Jones a job on X Factor.
Simon also - grudgingly - admitted that The Voice UK was an “interesting” format..
He told the newspaper about the new BBC One show: "I welcome it, to be honest.
"The competition will be good, and I will say, grudgingly, that their format is interesting."
Meanwhile Simon has been calling on Jessie to tune in to Britain’s Got Talent this evening.
He wrote to her on Twitter: "@jessiejofficial If you love talent please watch our show tonight. It proves Britain has got talent. Enjoy. X"
