Musk tells me about moving to Toronto when her children were teenagers, living in a rent-controlled apartment and struggling to buy clothes or furniture. It was there that she met Julia Perry, who has been her best friend and stylist ever since. “Now I can afford really nice clothes, the designers send them to me. I’m very honoured, but how times have changed. Now we live very comfortably, it’s been a long haul,” she adds.

Her tenacity and tireless work ethic have evidently rubbed off on her high-achieving children. Between modelling assignments, Musk spends much of her time supporting them in their endeavours; besides Elon and his quest for world domination, Tosca is a filmmaker and Kimbal is a restaurateur whose flagship project is building ‘learning gardens’ in schools across the US.

“I was at the premiere of Tosca’s movie last week, I was in Berlin for the big opening of Elon’s factory there and I go to the openings of as many of Kimbal’s vegetable gardens as I can,” she sighs. “I support all three of them on social media, too.”

By that she means, lobbying Joe Biden to take more notice of Tesla’s contribution to electric vehicle developments or hashtagging #proudmom when another of Elon’s posts sends shockwaves across the Twittersphere, as he’s done lately with proclamations about cryptocurrency or selling his stocks in Tesla according to whether his followers believe it’s a good idea.
