• Elon Musk’s current custody battle with Grimes hinges on where his children with the musician live.
• At a Formula 1 event in Texas, Musk was pictured waving to the crowd with his son X on his shoulders.
• The child is often pictured with his dad in Texas, but the photos take on a new resonance amid the custody dispute.

Tesla CEO Elon Musk made an appearance at Sunday’s F1 race in Austin, Texas, with his son X perched on his shoulders.

The 3-year-old is at the center of a parental rights battle between Musk and his sometimes-partner, musician Grimes. Musk filed his parental rights lawsuit against Grimes in Texas last month, seeking to “establish the parent-child relationship” with the three kids he shares with the musician. A few weeks later, Grimes filed her own suit in California, seeking primary physical custody and joint legal custody of the three children.
