The music mogul made hearts melt when he shared a candid shot of him enjoying some downtime with his young son Eric.
Lying in bed in a pair of casual grey tracksuit bottoms and a T-shirt, the X Factor boss can be seen holding up an iPad while little Eric lies on his chest and looks intently at the screen.
“After watching the Jungle Book 1000 times we have moved onto the Lion King,” Simon wrote.
The Britain’s Got Talent judge also revealed he’s determined to ensure Eric does not become spoiled.
He told the Daily Star Sunday newspaper: “I’m aware Eric could become a brat.
“I’m going to make sure we teach him manners and to not talk down to people. I’m terrible at discipline but that’s all basic stuff.
“And the first thing I said to Lauren is we’ll teach him to always be kind to animals.”
In fact, Simon pledged to have his son working at a young age, just as he did.
He revealed: “I’ll teach him the value of money. That’s what my mum and dad did with me.
“When they paid for holidays we had to earn our own spending money.
“When I was about eight I used to clean cars and mow lawns. And I used to love it.
“I do think it is important that you earn your own money.
“I had that instilled in me and Eric will have the same.”
