The X Factor judge, who became a dad himself last year, shared his words of wisdom this week after hearing the surprising news about One Direction's Louis.
Fans were super shocked this week when the news broke that American stylist Briana Jungwirth was expecting a baby with 1D singer Louis, 23, after a brief fling.
And Simon has now revealed that Louis went to him for advice...
Simon tells The Sun: "I said to him, 'You man up. You're fortunate because you're in a position to be able to look after the baby and not worry too much about that.'
"He didn't kill anyone. He got someone pregnant. It happens every day all over the world."
Simon also confirmed that the boys will take some time out next year.
In the same interview, media mogul Simon opens about his mother's recent death and her nine month battle with cancer.
He says: "It was a tough period but I didn't want to burden anyone else with my problem."
Julie passed away aged 89 on July 5.
