Elon Musk, engineer, industrial designer, technology entrepreneur, and philanthropist, has announced the arrival of a baby boy with his girlfriend, Claire Elise Boucher, known professionally as Grimes, a Canadian singer and pop musician.

The Tesla CEO shared the arrival of his son on Twitter and shared that baby boy and mom were doing great. A follower asked what the couple had chosen to name their son and Elon responded with a name that is quite unique, to say the least.

The meaning behind the name as well as the pronunciation remains a mystery. X Æ A-12 is certainly a name that is truly unique to this little boy! Of course, Elon is no stranger to using different names for his children, but this one definitely takes the cake!

Elon shares five children with his ex-wife, Canadian author Justine Wilson. They gave birth to their first child, a son named Nevada Alexander, in 2002. Sadly, Nevada passed away at 10-weeks-old from sudden infant death syndrome. The couple welcomed five more sons through in vitro fertilization. They welcomed twin boys in 2004 and named them Griffin and Xavier. In 2006, they welcomed a set of triplets, all boys, and named them Damien, Saxon, and Kai. Elon and Justine share custody of their five sons.
