Musk, who already has five sons from his previous marriage to author Justine Wilson, said that it was girlfriend and Canadian singer Grimes who had come up with the name for their son.

According to People magazine, a California family-law attorney had revealed that the state does not allow numbers or Roman numerals and symbols on birth certificates. The name must contain characters from the English alphabet, and that hyphens are allowed though the special character ‘Æ’ might prove a problem.

Musk and Grimes had welcomed their baby boy on May 4, 2020.
