The baby’s name had to be altered to comply with California law.

Grimes and Elon Musk have changed their new child’s name. The baby was born earlier this month and named X Æ A-12. Now, in order to comply with California law, which doesn’t allow numbers in names, the couple have altered their child’s name to X Æ A-Xii. Grimes explained the name change in the comments of a recent Instagram post, writing “Roman numerals. Looks better tbh.”

Shortly after they revealed the name, Grimes posted a breakdown of its meaning. “X, the unknown variable.Æ, my elven spelling of Ai (love &/or artificial intelligence), A-12 = precursor to SR-17 (our favorite aircraft).”
