Billionaire Elon Musk's estranged father Errol has admitted that he has a 10-month-old son with his stepdaughter Jana Bezuidenhout, who is 42 years younger. Jana was four when Errol married her mother Heide. Describing the baby as "God's plan", the 72-year-old said he didn't consider Jana his stepdaughter as she was raised away from the family for a long time.
