Asked whether he thinks Eric will venture into showbusiness like his daddy, Simon said: "100 percent. He's going to take over [from me]."
No pressure, then!
To make sure his little man is prepared to become Mr Nasty of the music biz, Simon revealed he has been teaching Eric, who was born earlier this year in Februrary, a thing or two.
Speaking to his close friend Terri Seymour on ITV's Lorraine earlier today, Simon said his son had been learning "a few of his naughty ways" and has been known to stick out his tongue at times.
But, not worried about having a mischievous child on his hands, Simon said: "I like it when they're naughty."
Hmm, we're not so sure mum will!
When he's not being influenced by his dad, Simon said Eric is the "happiest baby he has ever seen", even though he can't quite work out why considering he has a rep for not being very smiley...
He joked: "What happened?!"
As well as being busy with his parenting duties, Simon is judging this year's hopefuls on The X Factor. The music mogul has just picked his final three acts after auditioning the overs during his Judges' Houses at his pad in LA.
Going into the live shows, Simon has van driver Ben Haenow, now soloist Fleur East and former serviceman Jay James.
Speaking about his final three, Simon said: "Two were really easy [to pick] based on what we saw and then the third one was a little bit more tricky but then I slept on it and I made the right decision."
He added: "Ben was great, Fleur was a revelation on the day and Jay - he had an off day and then I thought back to his first audition and I thought, no, he deserves a chance. When I was talking to him giving him the news, 100 percent I felt it was the right decision."
Jay, Ben and Fleur will join Cheryl Fernandez-Versini's girls - Chloe Jasmin, Stephanie Nala and Lauren Platt, Mel B's boys - Andrea Faustini, Jake Quickenden and Paul Akister and Louis Walsh's groups - Only The Young, New Boy Band (yet to be named) and Blonde Electra.
Looking at the rest of the finalists for the show, Simon said he thinks the competition this year is going to be "close."
He said: "There is no clear front runner, there's a lot of people who could do well and I think the first live show you're going to really see who's got it and who hasn't."
The first of the live shows will kick off this weekend and each category's wildcard - rumoured to be pick by a different judge to the category's mentor - will finally be revealed.
Catch the X Factor live shows at 7.30pm this Saturday (11 October) and 8pm Sunday (12 October) on ITV.
