Calling out after he defended his fatherhood on X.

The author, 26, is currently suing the Tesla CEO, 53,  of an infant boy they reportedly share. In her petition, St. Clair alleged Musk has only seen the child, identified as R.S.C., three times since he was born in September 2024.

“This has never been about money for Ashley,” a representative for the 26-year-old author tells PEOPLE on Tuesday, Feb. 25. “This is about protecting the best interests of Ashley and Elon’s child from a man who can’t be counted on to even communicate, much less act consistently in the role of a father.”

“Mr. Musk spends more time on his own social media platform talking about his children’s mothers than talking to them,” the statement continues. “We tried to handle this collaboratively with Mr. Musk, but it takes both a father and a mother to do that, and he refused all conversations.“

PEOPLE reached out to Musk’s attorneys for comment.

St. Clair’s statement comes after YouTuber Jerry Rig Everything (real name Zach Nelson) slammed Musk on X, alleging he “Abandons a 5 month old. Won’t pay child support for another 3. And leaves the shield behind at major event… “

Jerry’s post accompanied a screenshot of a video of Musk walking down steps with his 4-year-old son,, trailing a few steps behind.

Musk  claims and called Jerry “an utter liar.”

“I have always paid extremely generous child support and without any coercion to do so,” Musk, who owns the social media platform X, replied. “Sometimes the mother asked for money vastly in excess of what the children could possibly need, so that needed to be adjudicated.”

St. Clair alleged in her legal filing that Musk first met R.S.C. in New York City on Sept. 21. He spent two hours with the baby before seeing him again the next day for one hour. Musk then saw R.S.C. for the “next and last time” in Austin, Texas, on Nov. 30, she claims. That visit allegedly only lasted 30 minutes.

St. Clair claimed she and Musk began a “romantic relationship” around May 2023 before allegedly conceiving R.S.C. in January 2024. She claimed that Musk “acknowledged parentage of the child in various written correspondences,” and included multiple text screenshots in her filing.

Musk allegedly told St. Clair via text in November 2024, “I want to knock you up again,” before texting her three months later: “Well, we do have a legion of kids to make.”

“Ashley St. Clair has filed paternity and custody petitions to protect the best interests of her child,” St. Clair’s representative told PEOPLE in a statement on Feb. 21. “She has made every effort to collaborate with Mr. Musk before taking this step. She has no further comment on the contents of the petitions, which speak for themselves.”

Musk has welcomed 13 children with four women, counting the alleged child with St. Clair.

He shares three children with his former partner Grimes, and is father to six other children with his ex-wife, Justine Wilson. Their eldest, Nevada Alexander, died of infant death syndrome (SIDS) at 10 weeks old. He shares three other children with Shivon Zilis, an executive at one of his companies.
