The Britain's Got Talent judge, 55, shared a rare snap of himself with his son Eric on Saturday (23 May) and it melted our hearts... Not something we thought TV's Mr Nasty could ever do!
In the snap, Simon is leaning over his toddler son who is staring up innocently into his super-famous daddy's eyes.
And hilariously, the pair appear to be in matching outfits!
Seeing the funny side, Simon tweeted: "No Eric. I said White shirt not t shirt."
Simon is clearly transforming his 15-month-old son into a little mini-me - should we be scared?

While we had a good nose at the bathroom for clues about the house Simon shares with partner Lauren Silverman, we were a bit disappointed when we realised the bathroom is probably in a hotel.
Simon told fans: "Away for the weekend. Watching King Kong. Doesn't get any better..."
Awwww, who could have guessed he'd love being a doting dad quite so much?
He became a father for the first time on Valentine's Day in 2014 after an on-off affair of several years with married Lauren.
Eric is named about Simon's late father.
He has previously admitted he'd like more children.
