President Donald Trump was left mesmerized by Elon Musk's son as the four-year-old stole the show at an Oval Office press conference.

The billionaire, 53, visited Trump, 78, on Tuesday accompanied by his young son X Æ A-12, also know as 'X.'

As the pair listened to Trump speak in front of a sea of photographers at the White House, the adorable tot clung to his father.

Musk, who was wearing all black with a matching black Make America Great Again hat, listened intently before chiming in with the president. 

His son, however, was the star of the show in his knee-length camel jacket, polo sweater, and collared undershirt.

The four-year-old also donned a thick gold chain that hung diagonally across his chest. 

While standing next to Trump, X made funny faces and stood playfully with his legs apart. 

When little X wasn't entertaining the journalists or laughing with his father, the four-year-old was nuzzling into his dad's hair while sitting on his shoulders. 

Both the President and Musk seemed largely unfazed by the cute outbursts.

In some images, the toddler was seen poking at his dad's cheek and sticking his little fingers in his ears.

And, in other snaps, X sat on his knees on the ground, gazing up at the rest of those gathered in the Oval Office.

Elon, who has 12 kids from three different women, welcomed X in May 2020 with his ex-girlfriend Grimes.

This isn't the first time that the SpaceX CEO has brought his son to a political event.

In December, the two were seen at Capital Hill in Washington, D.C., to meet with Senate Majority Leader John Thune.

He was also by his side at Donald Trump's Election Night celebration at Mar-a-Lago last month.

During Musk's interaction with Trump earlier today, he joked that the scrutiny the Department of Government Efficiency is receiving is like receiving a 'daily proctology exam.'

The meeting saw Trump signing a DOGE-centric executive order.

The order, which wasn't immediately released by the White House, was intended to 'significantly' scale back the federal workforce, pushing agencies to hire 'no more than one employee for every four employees' that depart, according to Semafor.

Trump didn't even bother signing the order in front of reporters, allowing Musk to hold court with his toddler for more than 30 minutes instead.

'And I fully expect to be scrutinized and get a daily proctology exam, basically,' Musk joked. 'Might as well just camp out there.'

Trump rubber-stamped what Musk was up to, telling reporters, 'We don't want an unsuccessful guy doing this.'

Musk scoffed when asked about his 'detractors' and said the American people voted for these cuts.

'I have detractors? I don't believe it,' the South African-born billionaire replied.
