Vivian Jenna Wilson, the 20-year-old estranged daughter of Tesla and SpaceX CEO Elon Musk, said she’s unsure of how many children her father has. In fact, she found out about an addition to her long line of siblings through social media.

Wilson sat down for an interview with Teen Vogue, in which she discussed her complicated family tree, revealing that it was a drag queen who indirectly informed her of Grimes giving birth to another one of Musk’s children.

“I found out about Grimes having a second child because a drag queen posted about it on Reddit. For a time, me and Grimes were not really in communication because I wasn’t in communication with anyone in that family, which still holds true,” she told the outlet. “Tatianna from RuPaul’s Drag Race Season 2 and RuPaul’s Drag Race: All-Stars 2 tweeted, “[Not] Grimes popp[in] out another axolotl,” which made the front-page of the RuPaul’s Drag Race subreddit, which is how I found out about it.”

Also in the interview, the 20-year-old was asked if she was on “good terms” with her siblings, in light of her having a strained relationship with her father: “That’s a question. I will say I do not actually know how many siblings I have, if you include half-siblings.”

Musk is reported to have up to 14 children between four different mothers over a 20-year span. The owner of X has six children, including Vivian, with ex-wife Justine Wilson; three children with Grimes; four children with Shivon Zilis, an executive at Neuralink (which Musk owns). Influencer Ashley St. Clair announced on February 14 that she gave birth to Musk’s 13th child. Two weeks later on February 28, Zilis was reported to have given birth to the billionaire’s 14th child.
