      The father, Elon Musk, is the world's second richest man, according to Forbes, with a net worth of US$184.3 billion.

      The mother, Grimes, is a Vancouver-born and raised singer, songwriter, record producer, and music video director.

      And their son, born on May 4, 2020, has one of the world's more unusual baby names.

      X Æ A-12 Musk is pronounced as "Ex Ash A Twelve". And this weekend, Musk tweeted a photo of them together.

      In an interview with podcaster Joe Rogan shortly after the child's birth, Musk explained that Grimes came up with "X" and "Æ" parts of the boy's name. A-12 was Musk's contribution.

      That's because according to Musk, the Archangel-12 was the coolest plane ever.

      It was a high-altitude reconnaissance aircraft retired in 1968. It was also known as the Lockheed A-12.

      Elon Musk explains to Joe Rogan how his son was named.
