Multi-billionaire tech mogul Elon Musk has posted the first picture of his newly-born son in response to demand coming from his fans, naming the baby ''X Æ A-12 Musk''.
Musk and his girlfriend Canadian singer Claire Boucher aka Grimes welcomed their first child together on Monday.
In response to a follower's tweet asking them to name the baby, Musk said: 'X Æ A-12 Musk,' making netizens to speculate on the meaning and pronunciation of the unique name.
Grimes confirmed the name, and explained the meaning in another tweet: "X is the ''the unknown variable'', Æ is her ''elven spelling of Ai", A-12 is the "precursor to SR-17".
"X, the unknown variable. Æ, my elven spelling of AI (love &/or Artificial intelligence), A-12 precursor to SR-17 (our favourite aircraft). No weapons, no defenses, just speed. Great in battle, but non-violent + (A=Archangel, my favourite song)," she posted.
Musk posted a photo of the baby through a tattoo/eyelash filter. "Never too young for some ink," he joked in a follow-up tweet.
As soon as Musk announced the baby's name, the internet went crazy. People across the globe started 'decoding' the name. While some were concerned about pronunciation, some wanted to know the exact meaning. Take a look at some reactions...
The Tesla and SpaceX CEO has six children with ex-wife Justine Wilson and this one is the first child with his new girlfriend.
Grimes announced that she was pregnant on Instagram in January.
During a live stream on Twitch in February, she said that the baby's due date was May 4.
Grimes also revealed she does not want to 'gender' her baby, saying they can "decide their fate and identity'' on their own accord.
