Tesla founder Elon Musk and musician Grimes welcomed their first child together, a boy, on Monday. Musk confirmed the baby's arrival in a tweet. "Mom & baby all good," he wrote.

Grimes, real name Claire Boucher, is a 32-year-old Canadian singer best known for her 2012 album Visions, that spawned the singles "Genesis" and "Oblivion." The album won the Juno Award for Electronic Album of the Year.

Grimes, who admits being a drug-addict-turned vegetarian, met Musk in 2018 after dating singer Devon Welsh for 3 years.

She broke the news of her pregnancy in a graphic photo on her Instagram page. The image showed her bare baby bump with what looked like red lacerations across her belly.
