If anyone has a more legendary life than the richest man himself, is his mother, Maye Musk, 76. She is the mother of richest man Elon Musk, and his two other siblings, who also are billionaires. Born in 1948, in South Africa, she is a model and a dietitian and has modelled for 50 years. She has appeared on the covers of several big magazines including Time magazine, Vogue, and Sports Illustrated. Amazingly enough, she made a comeback on the runway as a model in her 50s.
