Tesla co-founder Elon Musk and Canadian singer Grimes have welcomed their first child together.
Billionaire entrepreneur Musk, 48, shared the news on Twitter and said: “Mom & baby all good.”
He had earlier said the baby was “a few hours away”. Musk has since replied to a Twitter user and said Grimes gave birth to a boy.
In response to a Twitter user asking about the name, Musk replied to say he is called X Æ A-12 Musk.
There has been some speculation about the meaning of the name on Twitter, with Reddit users suggesting it could mean Ash or Sasha.
“The name for the ligature Æ is "ash"" one user wrote, "so in the name, it may be pronounced that way... and the Lockheed A-12 was part of the Archangel internal design effort.”
Grimes, 32, has been keeping fans updated throughout her pregnancy and in February revealed she had suffered “complications” and felt she was “woefully ill-prepared” to have a baby.
Later that month she told fans on Twitter she will allow the child to choose its own gender.
Musk and Grimes have been dating for more than two years and made their red carpet debut as a couple at the 2018 Met Gala.
South African-born Musk, one of the world’s most powerful and richest men, has five children with his first wife, the Canadian author Justine Wilson.
He has been in the headlines recently for his criticism of the coronavirus lockdown in the US.
He tweeted: “FREE AMERICA NOW.”
