Elon Musk's son X parties with Donald Trump on Election Night

Elon Musk brought his four-year-old son X with him to Donald Trump's Election Night watch party, and the youngster quickly became the star of the evening.

The Tesla CEO, 53, attended Donald's star-studded bash at his Mar-a-Lago estate on Tuesday evening, and he had a special guest with him: his son X Æ A-12, or 'X' for short, whom he shares with singer Grimes.

It may have been past the toddler's bedtime, but it looked like he had a great time as he partied alongside a slew of celebrities and political figures, munched on some yummy treats, and spent quality time with his famous father.

Photos showed little X smiling from ear to ear as he sat on his dad Elon's shoulders during the bash.

Another image featured X, who dressed in a miniature blue suit, snacking on some cookies.

Other attendees at the party included Dana White, RFK Jr., former presidential candidate Vivek Ramaswamy, Alabama Senator Tommy Tuberville, and Trump's attorney Alina Habba.

This isn't the first time that Elon has brought his son to a Trump event, as the mogul had X with him when he attended the GOP nominee's rally at Madison Square Garden last week. 

The youngster wore a customized red MAGA hat to the five-hour event, which read: 'Make voting great again.'

He was spotted holding up a Trump/Vance sign and chatting with former First Lady Melania Trump throughout the evening. 

Elon - who donated $75 million to his own pro-Trump super PAC - welcomed his son X in May 2020 with his ex-girlfriend Grimes.

They went on to welcome a baby girl named Exa Dark Sideræl in 2021, followed by son Techno Mechanicus in 2022.

After the birth of their daughter, Grimes told Vanity Fair that she was determined to keep her life as private as possible - unlike X.

She noted that her son 'is out there' because Elon was 'bringing him to everything,' and added that the businessman 'really sees' X as his 'protégé.'
