Elon Musk’s 4-year-old son added some levity to an otherwise serious meeting at the White House.

The tech billionaire, 53, brought his son X AE A-XII to meet with President Donald Trump before the commander-in-chief signed an executive order to slash the federal workforce on Tuesday.

Musk, who heads the Department of Government Efficiency, and the toddler stood behind Trump, 78, as they took photos in the Oval Office.

Musk threw on a black blazer atop a T-shirt for the meeting, while his son looked sharp in black trousers, a sweater and a camel coat.

X AE A-XII, who goes by X, put on a cheeky display despite being in the presence of the president.

The toddler was photographed flashing funny faces, flopping on the ground and climbing on his dad’s shoulders.

The group seemed to be in great spirits as they laughed and chatted about the little one’s antics.

However, this wasn’t the first time the tot met the head of state. Muskbrought X to Trump’s most recent New Year’s Eve party at Mar-a-Lago, where the CEO was captured dancing with his son on his shoulders.

While Musk is the father to 12 children, the Tesla founder rarely steps out with kids.

Musk welcomed six kids — late son Nevada, twins Griffin and Vivian, 20, and triplet sons Kai, Saxon and Damian, 19 — with his first wife, Justine Wilson.

He wed Wilson in January 2000 but they split after eight years of marriage.

Musk began dating singer Grimes, whose real name is Claire Elise Boucher, in May 2018 and they welcomed X — their son, not the social media platform — two years later.

Although the on-again, off-again couple split in September 2021, they welcomed daughter Exa Dark Sideræl Musk, who was given the nickname Y, via surrogate three months later.

They quietly had their thid child, Techno Mechanicus aka “Tau” around June 2022. However, they seem to be done for good as Grimes recently denounced her ex after his controversial appearance at Trump’s inauguration.

The exes have alsobeen locked in a contentious custody battle over their little ones, with the “Genesis” singer claiming she didn’t see one of her children for five months.

Meanwhile, Musk also shares 2-year-old twins, Strider and Azure, and and a 1-year-old child, whose name and sex has not been revealed, with Shivon Zilis.

His relationship status with the Neuralink director is unknown.
