Elon Musk is apparently drawn to unusual names. Take some of his children, for example. He reportedly has at least 12 kids with various partners. By far the most unorthodox names are those of the three children he shares with Grimes. Their older son, born in May 2020, is named X Æ A-Xii. While discussing this with Joe Rogan on his podcast, Elon said the couple landed on this name together.

"It's just X, the letter X, and then the 'Æ' is pronounced, 'Ash,' and then, 'A-12' is my contribution," he said.
