Simon Cowell already wants another child, according to Irish singer Kian Egan.
The new father - whose partner Lauren Silverman gave birth to his first son Eric in February - apparently told the Westlife singer he was keen to add to his growing family.
Kian told the Daily Star Sunday newspaper: "Simon seemed pretty excited and he told me he wanted to have another child fast. I told him to give him misses time to recover first.
"The thing about Simon is, it's all come as a surprise. Even when he got his dogs he didn't realise how much he would love them.
"I told him to wait until he has a baby and wait until that baby starts having its own personality then he's in a different place all together."
The singer also claimed the 'X Factor' boss will "stop working as much" once life as a parent sinks in.
He explained: "I think we will see a much softer side to Simon over the next few years. I think he will stop working as much and pull back."
Meanwhile, Simon has admitted his priorities have changed, with his baby boy giving him a fresh outlook on life.
He recently said: "I really, really am [happy]. I seem to come out of what I call a coma, which was just so work-focused.
"I can appreciated it now and enjoy it and have another side to my life, which I've never had before ... I think you can get very competitive.
"Everything in this business is about ratings and success. But it can take over your life a bit.
"It's still important to me, but it's not like it used to be. I suppose having a baby gives everything a purpose."
