TikTok star Kat Stickler rose to online fame before her relationships made headlines. Us Weekly exclusively reported in 2025 that Stickler and John Mayer were dating after being spotted dining in New York City together, per a photo obtained by DeuxMoi. But a source shared that she "doesn't think this will be a serious relationship." One year earlier, Stickler and Bachelor Nation's Jason Tartick announced their split. "I am sad to share that Kat and I are no longer together," Tartick wrote via his Instagram Story in October 2024.
