Who Is Kat Stickler? 5 Things About TikTok Star Dating John Mayer

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. “It’s fair to say that I love hard with all my heart and fall fast. Sometimes in life that works out and other times, it doesn’t. This time it didn’t.”

He continued, “Kat has brought me so much happiness and light, she brought out parts of me I never knew existed. I will forever be grateful for her and, of course [her daughter] sweet MK. This chapter closes amicably, and another opens.”

1. Stickler Used to Be Married

Stickler got engaged to ex-husband Mike Stickler in March 2019. By that May, the duo announced that they were officially married and expecting their first baby together. Their daughter was born in December 2019.

2.  Stickler Has a Daughter

Stickler posts mom content on social media with her daughter, Mary-Katherine (MK), 4, whom she shares with her ex-husband.

“MK will always be my number one priority. I consider my career in itself a parental responsibility, which helps alleviate some of that all too familiar mom guilt that finds its way to me whenever I’m away from her due to work commitments,” Stickler said in a June 2023 interview. “When I mom, my phone is put up and all of my attention is on her. When she is away at school or with her dad, I pour all of my focus into work.”

3. She’s a Budding Comedian

The internet star previously spoke about her dreams to become a comedian.

“Most of my comedic material is based on real life or inspired by people or ‘characters’ in my life,” she shared in the same interview. “I do my best to write down ideas when they come to me, either at 2 a.m. in bed, out with friends, or while doing whatever other miscellaneous activities. Once I have the idea written down, I run it by friends and family and see what comes off as the funniest, and most of the time we’re all laughing and building off of each other’s jokes.”

4. She’s Made Headlines in the Past

Prior to her rumored romance with Tartick, the influencer made headlines for a situation surrounding her daughter in June 2023. At the time, Stickler explained that she was at a park with MK when a birthday party nearby started singing “Happy Birthday.” When MK obtained a piece of cake, the mother hosting this party allegedly took the treat out of Stickler’s daughter’s hands.

“The mother takes the plate away from MK, and gets down to her level and says, ‘You can not eat this cake, OK? This is not your birthday party. These are not your friends. Where’s your mother?’” she recalled in a TikTok at the time. “I was right there. The mama bear in me was like, what just happened?”

5. Stickler Had Multiple Public Romances

After her divorce, Stickler went public with Cameron Walker in December 2021. However, they didn’t last long and split by August 2022.

She moved on with Tartick, with whom she dated for less than a year before their October 2024 split.
