In December 2021, a TikTok creator from the United States briefly became one of the most searched names on the internet. She had not gone viral for a dance video or a trending challenge. She had simply appeared, repeatedly and publicly, alongside one of the most famous young entertainers in the world — and the internet did what the internet does.
Katie Mills was already building a social media presence and playing soccer at the collegiate level when her name became linked to JoJo Siwa. What followed was a few weeks of intense public speculation, a quiet denial from Siwa at the start of 2022, and a brief but telling exchange that played out across TikTok comments. Since then, she has largely stepped back from that spotlight and returned to her own life.
Here is the full, factually grounded story of who she is and what actually happened.
Who Is Katie Mills? Her Background Before the Spotlight
Katie Mills is an American TikTok creator and college athlete. Before late 2021, her public profile was defined by the content she posted on social media and her involvement in soccer at Snow College in Ephraim, Utah, a small institution with a strong community college sports programme in central Utah.
Her TikTok content followed the format that drives most of the platform’s engagement: dance videos, lip-syncing to popular audio, and participation in whatever challenges happened to be trending at a given moment. By the time she attracted wider attention in 2021, she had accumulated over 100,000 followers, which represents a meaningful presence on the platform without placing her in the category of major creator.
What distinguished her trajectory from thousands of other TikTok creators at a similar follower count was what happened in December 2021.
The JoJo Siwa Connection: What Actually Happened
JoJo Siwa, the singer, dancer, and entertainer who rose to fame through YouTube and Nickelodeon
programming, had publicly come out as gay in January 2021. By the end of that year, she was one of the most-followed young celebrities in the world and every aspect of her personal life was subject to intense fan scrutiny.
In December 2021, videos and photos of Siwa and Katie Mills began circulating. The two were seen together in TikTok content, appearing to dance and spend time together. They were also photographed at a Los Angeles Lakers game, which is a sufficiently public setting that it effectively signals something to the people paying attention to celebrity social lives.
There were also sightings at Disneyland, which has a particular weight in the celebrity dating world as one of those locations that people rarely visit in ambiguous company. Videos showed moments of apparent closeness, including hand-holding, that fuelled the rumour cycle significantly.
Within a short period, the speculation had reached the level of mainstream celebrity gossip coverage, not just fan forums. The question of whether Siwa and the then-relatively-unknown TikTok creator were in a relationship became one of the more actively discussed celebrity stories of that month.
What Was Never Officially Confirmed
Neither Katie Mills nor JoJo Siwa ever issued a public statement confirming a romantic relationship. This is a detail worth holding onto clearly, because the volume of coverage that surrounded those December 2021 appearances can create a false impression of something more definitively established than it actually was.
On January 1, 2022, Siwa addressed her relationship status in a public statement saying she was single. That declaration effectively put an end to the speculation about the two of them specifically, without naming Katie or characterising whatever had passed between them.
The most accurate description of the situation, based on verified public information, is that the two were briefly linked, spent time together publicly, and generated significant dating speculation, but no official relationship confirmation was ever made by either party.
The Aftermath: A Brief Public Disagreement
What happened next is where the story gets slightly more textured, though still short on confirmed detail.
At some point in early 2022, Siwa posted a TikTok that referenced, without naming anyone directly, experiences with people she described as love bombers and clout chasers. The language was pointed enough that some viewers interpreted it as commentary on her recent personal life, though it was never addressed to anyone specifically by name.
Katie Mills responded publicly, and her response was direct. She questioned how someone could claim to care for another person and then simply ghost them. The comment was widely read as a reply to Siwa’s content, and it revealed that there had been at minimum a meaningful personal interaction between the two, even if the full shape of that interaction was never publicly defined.
The exchange was brief and did not escalate into anything prolonged. It remains the closest thing to direct acknowledgement from either side that something real had occurred between them.

Why This Story Keeps Coming Up
JoJo Siwa’s personal life has remained a point of sustained public interest since she came out in 2021. Every subsequent relationship, rumour, or near-relationship has been tracked with a level of attention that few entertainers her age have experienced. That means the people who were briefly associated with her during that period are consistently re-surfaced in searches and social media discussions, even when those associations were brief and unconfirmed.
Katie Mills sits in that category: someone whose personal story intersects with a larger celebrity narrative for a limited time, leaving behind a digital footprint that continues to generate curiosity long after the moment itself has passed.
It is also worth noting that she handled the public aspects of the situation with more composure than many people might manage. A brief public response, no extended drama, and a return to her own life. That is not always how these situations play out.
Conclusion
Katie Mills is a TikTok creator and college soccer player who became briefly and involuntarily part of a much larger celebrity story in late 2021. The connection with JoJo Siwa generated enormous public speculation, but no official relationship was ever confirmed by either party. What followed was a minor public exchange that suggested something personal had occurred, without defining what that was, and then both parties moved on.
Her story is a clear example of how proximity to celebrity works in the social media age: a short period of shared public space can generate lasting search traffic and ongoing public curiosity, regardless of whether the underlying situation was ever what observers assumed it to be.
Beyond that brief intersection with Siwa’s public life, she is a young woman building her own path through college athletics and content creation, largely out of the spotlight she briefly and unexpectedly occupied.
