The 61-year-old revealed that the 36-year-old recently divorced mother-of-one has had a great influence on Simon’s life.
Speaking about a possible return to the X Factor next year for the 53-year-old, Louis said of the media mogul:
‘He’s fantastic on the show because he makes everyone work hard. But he’s got to fit in looking after a baby now – and maybe getting married.
‘[Lauren]’s a great influence on his life – very positive and bubbly. She seems to have got the fun back into his life. They are like two teenagers dating. I love Lauren. I love all his girlfriends. He is what he is. I wouldn’t be here if it wasn’t for him.’
And it seems Simon Cowell is already a changed man.
The father-to-be opened up to a UK newspaper about impending parenthood, admitting:
‘I went to see a scan today and it is just surreal. You see this thing, which is now alive moving around. So I am happy.
‘Once it’s happened, you feel completely different. Once I heard the news about the baby – little bit of a shock, then I got used to it. Then I became incredibly paternal and protective and I feel very attached to the baby already.
‘The fact that it can happen at this time of my life is fantastic, maybe a miracle.’
We can’t wait to see Simon’s mini-me!
