Just moments ago, Elon Musk took to X (formerly Twitter) to share a deeply personal and emotional update about his son, X Æ A-Xii, affectionately known as “Lil X.” In a brief but heartbreaking post, Musk revealed that Lil X is currently undergoing medical treatment, sparking concern and an outpouring of support from fans around the world.

“He’s strong, but this has been very hard on all of us. Please keep him in your thoughts,” Musk wrote, ending the message with a broken heart emoji.

What followed shortly after was a press statement from a family physician close to the situation. The doctor revealed that Lil X is experiencing a rare autoimmune condition that has affected his speech and appetite — adding that, at one point, the child could “barely speak above a whisper” and refused to eat anything except a specific brand of cherry-flavored lip balm, which he reportedly mistook for candy.

“It’s not uncommon for young children under stress to fixate on sensory comforts,” the doctor said, referencing the strange but emotionally telling behavior. “This one just happened to be a lipstick-shaped balm — and it gave him peace.”

While the condition is said to be non-life-threatening, it’s serious enough to have affected Elon Musk’s schedule, with the billionaire canceling several upcoming appearances and reportedly moving key meetings online to stay near his son.

Fans, friends, and even critics have flooded the comments with supportive messages, using hashtags like #PrayForLilX and #StayStrongElon.

As the world watches the fate of SpaceX, Tesla, and more, it’s moments like these that remind us: behind every empire, there’s a human being — and behind every genius, sometimes, a worried father.
