ELON MUSK and GRIMES tweaked their son's name so it complies with California law.

Earlier this month, the couple revealed that they named their newborn son X Æ A-12. Still don't get it? Ya, same.

As its turns out, that name didn't comply with California Laws. On an Instagram post on Sunday, Grimes was asked by a fan if she had changed her son's name. Grimes confirmed they had writing back to the fan, "X Æ A-Xii”. huh?
