Musk's first wife, Justine Wilson, is a fantasy and sci-fi author with whom he had six children. Their first child, Nevada Alexander Musk, was born in 2002 but tragically died due to Sudden Infant Death Syndrome. The couple later had twins, Griffin and Vivian, in 2004, followed by triplets, Kai, Saxon and Damian, in 2006.

Grimes, who has accused Musk of keeping her children from her, has recently disavowed the tech entrepreneur’s politics and criticized him for bringing X Æ A-Xii, nicknamed X, to the White House for a photo op with Trump in the Oval Office earlier this month.
