Elon Musk and his ex-wife, Justine Wilson, run in separate circles, their daughter, Vivian Wilson, said in a new interview. The Tesla CEO and the novelist and short story author — who share six children total — tied the knot in 2000 before separating in 2008.

Musk also shares four children — Strider, Azure, Arcadia, and Seldon Lycurgus — with Neuralink executive Shivon Zilis, as well as three kids — X Æ A-Xii, Exa Dark Sideræl, and Tau Techno Mechanicus — with music artist Grimes.
