How many kids does Elon Musk have?

Many were under the impression that he had 10 children altogether, but a new biography by Walter Isaacson claimed that he actually had 11.

Who are Elon Musk's children?

Musk's kids include: 

Nevada Alexander Musk

Musk's first child was Nevada Alexander Musk.

He was born in 2002, two years after he married Canadian author, Justine Wilson.

Sadly, Nevada died at just 10 weeks old of sudden infant death syndrome.

Griffin and Xavier Musk

In 2004, Musk and then-wife Justine welcomed twins Griffin and Xavier with some help from IVF.

In June 2022, Xavier filed a petition to change her gender as she wanted to be unrelated to her biological dad.

Xavier filed the paperwork in California on April 18 to change her name.

The petition reveals that she wants to be known as Vivian Jenna Wilson, reported.

She said she's changing her name because she "no longer lives with or wish to be related" to her biological father "in any way, shape or form."

Kai, Saxon and Damian Musk

The former couple's triplets, Kai, Saxon, and Damian Musk, were born in 2006.

They too were conceived through IVF and custody is shared between the two parents after they divorced in 2008.

Musk has never spoken publicly about his life with his sons.

In a previous interview, Wilson said: "Almost all of my non-work waking hours are spent with my boys, and they are the love of my life."

X Æ A-Xii

In May 2020, Musk and his former partner, Grimes, announced the arrival of their little boy.

He was born on May 4, 2020. 

The pair initially named their newborn child X Æ A-12.

The name appeared to be partially inspired by one of the songs from Grimes' last album, 4ÆM.

Unfortunately for the couple, the name was not in accordance with Californian state law, as the law prohibits Indo-Arabic numerals in names.

Musk and Grimes had to change it to X AE A-XII to remove the Æ and 12 so that his birth certificate would comply with California law.

In an interview for Joe Rogan's podcast at the time, Musk revealed the pronunciation of his son's name.

He told Rogan that it is pronounced X-Ash-A-Twelve.
