Elon Musk and his 3-year-old son, X AE A-XII, whom he shares with Grimes, had the greatest father-son time.

Musk spent Sunday at the Formula 1 Grand Prix in Austin, Texas, with his 3-year-old son.

The infant wore a blue T-shirt, pants, and sneakers while riding on his father’s shoulders in a golf cart.

The Tesla magnate arrived at the Circuit of the Americas wearing an all-black outfit.

According to Page Six, “Elon arrived in the paddock more than an hour after the race began,” as per a report from a source.

“He was smiling and laughing with a few friends before putting X on his shoulders and walking to the Mercedes garage,” the source said.

Musk’s excursion with his son follows a lawsuit filed by Grimes and the Tesla magnate for X and his siblings’ parental rights.

In December 2021, the ex-couple delivered their one-year-old daughter Exa Dark Sidereel through a surrogate.

According to a September New York Times review of Walter Isaacson’s biography of Elon Musk, the couple is also the parents of a child named Techno Mechanicus. The baby’s name, gender, and date of birth are undisclosed at this time.

On September 13, the 52-year-old businessman filed a petition in Texas seeking legal guardianship of their children.

On September 29 in California, Grimes, 35, followed suit.
