Exa Dark Siderl Musk, her 9-month-old daughter, appeared on Twitter on Sept. 18 and said she is about to make a move. “My daughter is dancing to techno over this photo of Nietzsche's birth of tragedy.” she wrote alongside the photo.
Exa is Grimes' second child, and he was born four months after their husband announced his plan to have another child.
Exa Dark Siderl Musk, a supercomputer specialist, was introduced to Vanity Fair in March. “Exa is a reference to the exaFLOPS technology, which allows for the execution of 1 trillion floating-point calculations per second.” She explained how to pronounce Siderl, and that the name is associated with "the true time of the universe, star time, deep space time, and our relative earth time."
Grimes admitted that she and Elon, who had been dating on and off since 2018, were still together and "always desired at least three or four" kids during the Vanity Fair interview. However, they were separated by the time the interview was published.
Elon shares five other children with his ex-wife, Justine Wilson, whom he married between 2000 and 2008. Nevada passed away unexpectedly at the age of 10 weeks old due to sudden infant mortality syndrome.
