After Elon Musk’s 4-year-old son — X Æ A-Xii, known as X — made an appearance in the Oval Office Tuesday with his dad and President Donald Trump, videos of the child’s antics have gone viral online.

X stole the show from Trump and Musk’s first public comments in front of camera crews and reporters, ABC News reported.

“This is X, and he’s a great guy — high IQ,” Trump said at the top of his remarks, chuckling and calling the 4-year-old a “high-IQ individual,” the outlet said.

While defending his Department of Government Efficiency efforts, ABC News said, Musk repeatedly got distracted, including after he hoisted his son to his shoulders and X played with his father’s ears.

X also made faces and mimicked his dad’s gestures as he spoke with the press.

Also during the press conference, X made monster noises and picked his nose while leaning over the famed Resolute Desk in the Oval Office, Today reported.

There has also been speculation as to what X said to Trump in the Oval Office, Newsweek reported. Some thought he said, “You’re not the president, and you need to go away.”

Born in 2020, “Lil X” — as his father calls him — is the youngest son of Musk and Canadian musician Grimes. Previously, he’s occasionally been spotted alongside Musk in public, including election night, where he was featured in the Trump family photo and was called “a gorgeous, perfect boy” by the president, the outlet said.

Grimes expressed her disapproval of X’s public appearance on social media.

“I am not him,” she wrote of Musk, according to Today. “I will not make a statement every time he does something.”

She added, “To be clear, I could go talk (expletive) and be on a bunch of magazine covers and be a feminist hero and get clout — but it would serve no purpose. I choose my children’s wellbeing.”
