He turns 90 in a matter of months but Bernie Ecclestone is determined to have even more children.
The 89-year-old ex-Formula One boss and wife Fabiana Flosi, 44, welcomed baby Alexander Charles Ecclestone on Wednesday.
He hit back at those who say he is too old to be a dad to the boy they call Ace – and vowed to be the perfect parent to the new arrival.
The baby’s siblings are aged 65, 35 and 31 – but he may have someone more his own age to play with in the near future.
Speaking to The Sun, the magnate said: “Now I have more time on my hands and I hope I can spend it with my son as he grows up.
“I don’t know if we will stop here. Perhaps he should have a little brother or sister?”
Asked if he has any help in the bedroom, he replied: “Do I take anything? No! Fabiana gives me some tablets — vitamin D — but I don’t take anything else.”
Bernie already has lots of experience raising children as he has three children from his previous marriages and five grandchildren.
His eldest Deborah, 65, was born to his first wife Ivy Bamford.
The mega-rich businessman then welcomed daughters Tamara, 35, and Petra, 31, with second wife Slavica Radic.
Speaking last week to the Daily Mail, the tycoon said: “I just hope I live long enough to see as much of our baby as I can.
“It’s all very good, I am very happy. It’s different now.
“I’m more relaxed and my work is not so pressured so I can spend more time with him.”
When asked if he’d be changing nappies, he replied: “I doubt it. I will do what is asked.”
Bernie is now worth £2.5billion, according to the most recent Sunday Times Rich List.
