Elon Musk’s daughter isn’t hiding her surprise.
After tech executive Shivon Zilis confirmed she welcomed her fourth baby with the Tesla CEO, his 14th overall child across relationships with Shivon, exes Grimes and Justine Wilson, as well as author Ashley St. Clair, his 21-year-old daughter Vivian weighed in.
Vivian—who Elon shares with ex Justine, along with her twin Griffin, 20-year-old triplets Kai, Saxon and Damian, and late sibling Nevada—stitched a previous Feb. 15 video where she pokes fun at finding out about her father’s other children, adding in a new March 1 TikTok, “This is already outdated nevermind.”
The side-by-side stitched video also shows Vivian placing her eye all the way up to the camera lens, making a disappointed expression.
“Wow, if I had a nickel for every time I found out I had half-siblings through Reddit,” she’d written in the original video, also dubbing the similar line from Phineas and Ferb, “I’d have two nickels…which isn’t a lot, but it’s weird that it happened twice, right?”
The 21-year-old’s video is just the latest time she has called out the unusual dynamics that persist in her family. In another prior TikTok from Feb. 15, Vivian—who does not have a relationship with the SpaceX executive—shared that she had found out about the birth of Elon and Grimes’ now-2-year-old Techno Mechanicus in 2022 through a RuPaul’s Drag Race subthread on Reddit. (The former couple also share X Æ A-12, 4, Exa Dark Sideræl, 3.)
“At the moment, I’m just in complete shock and I don’t believe it,” Vivian recalled of the memory. “So I double check it on the news and turns out it’s actually f–king true and I am just the last one to find out about it. This is a real thing that happened to me.”
Of course, Vivian isn’t the only one in Elon’s family to find out about updates through the news cycle. Grimes previously expressed frustration after seeing her eldest appear at the White House Oval Office alongside his dad and President Donald Trump.
“He should not be in public like this,” Grimes wrote on X after a fan signaled her about her “very polite” son’s White House visit. “I did not see this, thank u for alerting me. But I’m glad he was polite. Sigh.”
