The twins were born in November in Austin, Texas, according to Business Insider. They were born just weeks before Musk and Claire Boucher, the musician known as Grimes, had their second child via surrogate in December.
In April, Musk and Zilis filed a petition to give the twins their father’s last name and their mother’s last name as part of their middle name, according to court documents.
The news brings Musk’s total count of children to nine. Musk shares two children with Grimes. He also has five kids with his ex-wife Canadian author Justine Wilson.
Musk who tweets regularly, hadn’t been heard from in nine days until last week when he broke his silence on a trip to Italy where he was shown in a photo with his four sons and Pope Francis.
