Elon Musk, Donald Trump's head of DOGE, made comments about being 'a meme' during an appearance at the Conservative Political Action Conference on the same day ex-partner Grimes pleaded for him to help with their child's 'medical crisis.

"I would really like people to stop posting images of my kid everywhere," said Grimes Amid Elon Musk's new role as head of the Department of Government Efficiency, Grimes hopes her children will be kept out of the spotlight.

Just as an erratically behaved Elon Musk took the stage at a conservative conference in Washington, D.C., his ex-girlfriend Grimes was begging him on X to address an urgent medical crisis involving one of their three children.

In the BBC docu-series The Elon Musk Show, reporter Devin Gordon claimed 36-year-old Grimes had shared the news with him personally. "She [Grimes] told me repeatedly that Musk has this theory of her that she’s not real," Gordon claimed at the time.

Grimes, Elon Musk’s ex-girlfriend and mother of three of his children, recently took to social media to express her opinions about the “unhinged mode” of Grok 3, an AI chatbot launched by the tech billionaire’s company xAI.

The “Genesis” singer and the billionaire are parents to three children: X Æ A-Xii, Techno Mechanicus and Exa Dark Sideræl.

Grimes has issued a plea about 'consent' following her son, 'Little X', appearing at The White House with his dad, Elon Musk.
