Elon Musk and Grimes welcome baby

Some theories have already been floated about what that name means, including one guess that it's Sascha 12.

Grimes is mother to a baby boy, her first child with tech mogul Elon Musk, who shared the first pictures of the tot on social media on Monday night (04May20).

After revealing to fans that his girlfriend was due on Monday, he updated fans yesterday, "Mom & baby all good". The entrepreneur and philanthropist, Musk also shared a cryptic tweet about the name of his newborn baby boy.

We have no idea how to pronounce that either. It's hard to tell whether Musk will really name the child X Æ A-12 as the entrepreneur is quite the prankster. However, he couldn't resist having a little fun with his fans and posted another picture of the child with several fake face tattoos.

The couple first announced they were expecting a child together in January, with the 48-year-old being confirmed as the father in March. This prompted one fan to ask: "A pic of you holding the baby would break the internet. please share one", and Elon happily obliged. Musk has two twin boys and another set of triplet sons from a previous marriage.
