Elon Musk has allegedly fathered a pair of secret twins, new court documents have revealed.
According to the documents obtained by Insider, the tech mogul very quietly had twins with Neuralink executive Shivon Zilis.
The world's richest man has spoken multiple times about global population and his belief that people should be having more children.

Musk is now the father of nine children in total.
According to Insider, Musk, 51, and Zilis, 36, filed a petition in April to change the twins' names.
The documents, cited by Insider, said that the change was to reflect 'their father's last name and contain their mother's last name as part of their middle name'.
The order to change the babies' names was approved by a judge in Texas in May.

The twins were born only weeks before Musk and his ex-partner Claire Boucher - known as the musician Grimes - welcomed their second child via surrogate in December.
Musk and Boucher have since split.
Zilis, originally from Canada, began her career at IBM and joined venture-capital fund Bloomberg Beta in its early stages.
She was also on Forbes' 30 Under 30 list in the venture-capital category in 2015, so she is one hell of an impressive woman.

According to Insider, Zilis and Musk met during her time at OpenAI.
OpenAI is an artificial intelligence research laboratory with the goal to ensure that artificial general intelligence benefits all of humanity.
It was co-founded by Musk in 2015 and she served on the board as the youngest person on OpenAI's board of directors.
She moved to Tesla in 2017, and now works for Neuralink, of which Musk is a co-CEO.

According to Insider, during Zilis' tenure at Neuralink, the company conducted surgical trials of its Bluetooth-enabled brain chips on monkeys.
This led to a nine-year-old macaque to play the video game Pong using only its brain.
Musk has hinted that human trials could start by the end of 2022, as per Insider.
Zillis now lives in Austin, Texas, in a home under both her name and Musks.

She moved into the gated-community home about three months before the twins were born.
Musk and Zillis are yet to publicly comment on their new arrivals.
UNILAD has reached out to Neuralink for a comment on Insider's report.
