This explains the nice change of heart...
And just how he gushes over two-year-old Eric might just be proof that Mr Cowell has gone all soft.
The music mogul has admitted that he brings the little guy – who he had with partner Lauren Silverman – to America’s Got Talent auditions and he uses Eric’s tastes to help him judge.
Speaking to PEOPLE magazine, the 56-year-old said: ‘He’s the world’s cutest little boy. I’ve got to tell you, he’s going to be my little right-hand man – anything he likes I like. He’s brilliant, he comes down to the auditions and really enjoys the acts.
‘He’s very good to watch, funnily enough, because I can see when he’s bored and when he’s up dancing. He’s a good critic already. He’s unpaid, but he’s helping me!’
So that’s one way to beat the judging super-villain: make his son happy, and you’re through to the next round.
And it’s not just his boy that’s making him all soft – he even admitted to feeling like a new boy on the judging panel that he put together. The judge is joinging Heidi Klum, Mel B and Howie Mandel on this year’s panel.
‘What was funny was that I felt like the new boy on AGT because these guys have worked together for so long. They kept kidding that I was the boss.
‘I thought they were the boss and I was the new boy who has gone to a new school and hoped they liked me. Actually we got on brilliantly – it was much, much easier than I thought it was going to be.’
Ohhh, you big softie. What happened to the original Mr Nasty?
