"Fabiana would like so much to have a baby. But I'm 83, so it wouldn't be fair on the child," said Ecclestone.
"Imagine, the child is six, goes to school, and then its 90-year-old father comes to pick it up. You can't do that to a child," he insisted.
Ecclestone also claimed that, although worth billions and bankrolling the extravagant lifestyles of his daughters Tamara and Petra, making money is not his main motivation.
"Money doesn't talk to me, it doesn't make me laugh," he said.
"I'm just lucky that I have enough that I don't have to worry about making it," Ecclestone explained. "But I'm not trying to accumulate more and more.
"If I make a good deal, I am satisfied," he added.
