Elon Musk and girlfriend welcome first child together

SpaceX founder and CEO, Elon Musk and girlfriend have welcomed their first child.

Musk announced the news on Twitter. After tweeting about something completely unrelated (EPA testing on the Tesla Model S) someone asked Musk for news on the baby. First he replied "a few hours away," reported Daily Mail.

Four hours later, Musk replied to his own tweet to announce, "Mom & baby all good."

Later, Musk confirmed the baby was a boy.

Later, Elon had taken the decision to post the image after a fan wrote: "A pic of you holding the baby would break the internet ... please share one."

Musk, 48, has been dating the musician Grimes since 2018.

Grimes, 32, whose real name is Claire Boucher, announced she was pregnant in January on Instagram. She shared a topless photo of herself with a baby bump and wrote in the caption that "being knocked up is a very feral & war-like state of being."

The couple made waves with their first public appearance together at the Met Gala in 2018, surprising both the music and business worlds. Grimes wore a choker shaped like the Tesla logo to further demonstrate their relationship status.

Musk, known for his grand ambition and brash demeanor, had already been in the news the past week when he went on a Twitter rant that included saying Tesla's stock was overvalued. The comment sent shares of the electric carmaker tumbling.
