Elon Musk welcomed twins with one of top executives weeks before he welcomed child with Grimes

Elon Musk quietly welcomed twins with one of top executives, 36, weeks before he welcomed a child with Grimes via surrogate, court documents revealed. 

Last November, the Tesla CEO, 51, welcomed twins with one of his top executives, Shivon Zilis, 36, Insider reported. He now has nine known children.

Musk and Zilis filed a petition in April to change the twins’ names in order to ‘have their father’s last name and contain their mother’s last name as part of their middle name,’ it was reported.  

The twins were born in November, just weeks before Musk and Claire Boucher, who performs as Grimes, had their second child via surrogate in December. 

Zilis is a rising star in Musk’s empire. Born in Markham, Ontario, Zilis received her bachelor’s degree in economics and philosophy in 2008 from Yale, where she also played goalie on the women’s ice-hockey team. A lifelong athlete, she has been pictured on social media surfing, zip-lining, and ice climbing. After beginning her career at IBM, she joined the early-stage venture-capital fund Bloomberg Beta, where she led investment efforts in data and machine learning. She was on Forbes’ 30 Under 30 list in the venture-capital category in 2015.
