Elon Musk Shares a Rare Photo Posing with His Son X AE A-Xii — See How Similar They Look

On Saturday, the world's richest man Elon Musk surprised many when he shared a rare but adorable picture of himself and his nine-month-old son, X Æ A-XII.

Tesla CEO Elon Musk continues to make great strides in technological advancements and innovations, which has seen him rise to the number one spot on the list of the world's richest men.

However, his job's busy nature does not stop him from babysitting his nine-month-old son, X Æ A-XII, as shown in a tweet he made over the weekend.

Musk tweeted a picture that showed him carrying the adorable X Æ A-XII, who licked his lips while tugging at his famous father's gray t-shirt. The little tot was topless, wearing only his napkin.

Meanwhile, Musk was also seen answering a phone call while holding on to his son, who he placed on his lap. In the caption to the tweet, the loving father wrote:

"The Second Last Kingdom."

Musk shares the cute X Æ A-XII with his girlfriend, singer Grimes. The couple welcomed their son in May 2020, amid the COVID-19 pandemic.

They initially named him "X Æ A-12" Musk but changed his name to X Æ A-XII because California law does not allow special characters and numbers to be used in names.

He was candid about it in a reported interview, revealing his heartbreak over he and his ex-girlfriend, Amber Heard's breakup

The billionaire's son's name has generated many questions from people regarding its pronunciation. However, Musk explained the unique name's meaning while appearing on a podcast with comedian Joe Rogan.

The SpaceX CEO revealed that Grimes came up with their son's name. He also said that "X" is just the alphabetical letter X, while Æ is pronounced as "Ash."

Musk further explained that A-12 is his contribution to the name and stands for "Archangel 12, the precursor to the SR-71, which he said was the coolest plane ever.

Though he explained the meaning behind his son's unique name, Musk is usually quiet about details of his personal life. However, he was candid about it in a reported interview, revealing his heartbreak over his and his ex-girlfriend, Amber Heard's breakup.

He also touched upon his estranged relationship with his dad, Errol, who he described as a terrible human being, adding that he committed so many crimes.

Besides X Æ A-XII, Musk also shares five teenage sons, including twins and triplets, with his former wife, Justin Wilson, whom he tied the knot with in 2000 before splitting in 2008.
