The concept of 'miracle babies' is often raised by those who conceive after forty, and you can add Iman to the list of people who believe in them. She'd had a child much earlier in life, when she was still in her twenties, during her first marriage to basketball star Spencer Haywood. Later, and more famously, she married the late, legendary British rock star David Bowie.
The couple did try to have a child of their own the natural way, but nothing seemed to be working, including IVF treatment. Like many others, they were considering adoption when, at the age of 45, Iman spontaneously became pregnant and gave birth to their daughter Alexandria. That was back in the year 2000, meaning that Alexandria is now an adult in her own right. By that point, Bowie was 53, making his own fertility even less likely than Iman's; but then nothing about Bowie was ever normal.
