Elon Musk’s 2-Year-Old Son X Looks So Grown Up While Attending Miami Conference With Him

Elon Musk is showing his youngest son X Æ A-XII all about the family business! The 51-year-old SpaceX founder was spotted at the MMA Global POSSIBLE Conference in Miami, Florida on Tuesday with his 2-year-old son by his side in rare photos. The little boy looked cute as can be, rocking a grey t-shirt with navy blue pants and sneakers, while Elon was dressed up in a white button-down shirt under a black sport coat but more relaxed with no tie. The Tesla mogul shares X and 16-month-old daughter Exa Dark Sideræl, who goes by Y, with his ex-girlfriend, Grimes.
