Elon Musk’s mom has some unusual sleeping arrangements while visiting her son.

The 74-year-old supermodel said she wasn’t sleeping in an actual bedroom when she visited the SpaceX CEO in Boca Chica, home of the company’s Texas headquarters and Starbase launch site.

“I had to sleep in the garage,” she told the outlet. “You can’t have a fancy house near a missile base.”

Elon says he doesn’t have a “primary residence,” though he lives in a “very small” $45,000 house in Boca Chica.
