Elon Musk holds his son X Æ A-12's hand on stage at an event.

Musk pointed out that he was doing his part when he lamented the decline of the America's birthrate. According to an Insider report, Musk had secret twins last year, bringing the total of his brood to nine.

According to Insider, Musk welcomed twins on the down low with a Neuralink executive a month before he and his wife had a baby. According to court documents, Musk is the father of the twins and the mother is the one who wants to change their last name to Musk. The petition was approved in the month of May. The documents had Musk's signature on them.

CNN reported on Thursday that it had obtained a docket from a Texas court that confirmed the name change petition.
