(The Hill) – Tech billionaire Elon Musk and conservative influencer Ashley St. Clair publicly feuded on X on Monday after she accused the world’s richest man of withdrawing childcare support and refusing to take a paternity test.

Musk defended himself against those claims, saying he has given St. Clair more than $2 million and is open to a paternity test.

“I don’t know if the child is mine or not, but am not against finding out. No court order is needed,” Musk said in a post on X, responding to reporting that a court has ordered him to take a paternity test.

“Despite not knowing for sure, I have given Ashley $2.5M and am sending her $500k/year,” he added.

Musk’s comments came after St. Clair was seen selling her Tesla, saying she was doing so after Musk allegedly cut childcare payments.

St. Clair shot back at Musk for saying a court is not necessary for him to take a paternity test, saying, “Elon, we asked you to confirm paternity through a test before our child (who you named) was even born. You refused.”

She also addressed his claims related to continued childcare support.

“And you weren’t sending me money, you were sending support for your child that you thought was necessary… until you withdrew most of it to maintain control and punish me for ‘disobedience,’” she continued in her post on X on Monday. “But you’re really only punishing your son.”

St. Clair attacked Musk for using his social media platform “to distribute derogatory messages about me and our child to the entire world.”

“It’s all about control with you, and everyone can see it. America needs you to grow up, you petulant man-child,” she added.
