ELON Musk made an adorable outing with his rarely-seen son as the two attended a football game together.

The billionaire shared a video of the game against the Army Black Knights and Navy Midshipmen on Saturday at Gillette Stadium in Massachusetts.

Known as America’s Game, it will be the first time the game is held in the state as both the Naval Academy and Army West Point announced that they will cycle cities for the next five years.

“ARMY-NAVY,” Musk tweeted with several American flag emojis.

But what really stole the show were photos of Musk, 52, with his three-year-old son, X AE A-XII, perched on his shoulders.

Musk smiled at the camera as he walked with his son, who he shares with singer, Grimes, throughout the stadium.

X AE A-XII wore a green plaid shirt, jeans, and sneakers as he held onto his father.

The father and son posed with the Army Mules, the mascot for the Army Black Knights, whom Musk was supporting.

The Army Black Knights beat the Navy Midshipmen with a score of 17 to 11.

TWINNING

Last summer, Musk shared a photo of him and X AE A-XII with matching haircuts.

He captioned the post: “Thanksgiving last year after watching one too many episodes of Vikings.”

The image went viral on X, formerly known as Twitter, and it gained almost 300,00 likes in less than 24 hours.

One fan asked: “Did you cut your hair And his”.

Musk simply replied: “Yeah”.

X AE A-XII is the eldest of three children, Musk shares with his former girlfriend, Grimes – real name, Claire Elise Boucher.

The child’s name was originally, X Æ A-12, but it had to be changed when it was revealed that using “Æ” and “12” violated naming laws in California.

The couple also have a daughter Exa Dark Sideræl Musk, born via surrogate, and their youngest son, Techno Mechanicus Musk.
