Influencer and comedian Kat Stickler has routinely kept her fans guessing when it comes to her love life.
The TikTok star rose to fame during the pandemic alongside her husband, Mike Stickler, through posting family content. The pair split personally and professionally not long after, however, in early 2021. (Mike and Kat are parents to one daughter, Mary-Katherine a.k.a. MK.)
After her divorce, Kat dated Bachelor Nation star Jason Tartick for five months in 2024, during which time they developed a huge following courtesy of their adorable couples content. To many fans’ surprise, Kat and Tartick split in October 2024, and she was later linked romantically to singer-songwriter John Mayer.
“It just didn’t work … I don’t want to talk about it,” Stickler told TikTok followers about her split from Tartick. “I understand that with posting a relationship online you also have to show this side, the aftermath — Woohoo, so fun I love this!”

She went on, “But I just wanted to tell you guys and it’s not love wasted. I feel like sometimes it’s so easy to think that when a relationship ends that the love is wasted. But love is never wasted. So, that’s all I have to say.”

Mike Stickler
Kat filmed TikTok videos during the COVID-19 pandemic showcasing her and her husband frequently pulling off light-hearted pranks with their daughter, MK. As part of their videos, the couple shared that they got engaged and later married and were expecting MK all within three months in 2019.
After fans noticed in early 2021 that Kat was mostly posting solo content on the couple’s account, she and Mike sat down for a joint video where they addressed split rumors.
“Unfortunately, [the rumors] are true,” she explained to viewers. “We are separating. We just wanted to be transparent with you guys, because you guys have been with us from the beginning of this whole journey.”

Four years after the split, Kat hit back at speculation and criticism over her post-divorce dating life.
“I have had two serious relationships post-divorce, which was five years ago,” Kat pointed out via Instagram. “If I really cared what people thought, a) I probably wouldn’t do this for work. But b) I probably would still be married!”
Cameron Walker
One of the two serious relationships Kat seemingly alluded to in her 2025 clapback was her nine month romance with Walker between December 2021 and August 2022.
Kat later explained to her social media followers that it didn’t work out with Walker because she’d jumped into a relationship too quickly following her divorce from Mike.
Jason Tartick
Kat met and hit it off with the Bachelor Nation alum while guesting on his podcast “Trading Secrets” in April 2024. Once the pair went “Instagram Official” in June 2024, Kat and Tartick quickly became one of the internet’s favorite couples.
Fans excitedly followed along as they documented major milestones — including Tartick introducing Kat to his parents — via social media. Unfortunately, Tartick stunned fans in October 2024 by confirming he and Kat had gone their separate ways.
“I am sad to share that Kat and I are no longer together,” Tartick wrote via Instagram Story. “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.”
Tartick once again spoke out when fans suspected that the breakup may have been faked for one of their viral prank videos.

Kat released her own response when people were critical of her decision to introduce her young daughter MK to Tartick so soon into their relationship. The influencer confirmed that her ex-boyfriend — whom she did not name in the post — had spent time with MK, and that her daughter also met Stickler’s “male friends” and “the husbands of my girlfriends.”

“Three things, she’s always with me when these males are introduced in her life, and they are always introduced as mommy’s friends,” Stickler insisted. “She doesn’t call anyone dad. She has a dad [and] that is never a point of confusion for her, and I promise you guys, she is OK.”
She added, “I just hope that MK knows I am looking to find the right partner for the both of us, because we are a package deal. And I know I don’t always make the right decision, but I learn from my mistakes and every decision that I do make, it’s because it’s what I think is best for my daughter and I.”
Mystery Man
Kat intrigued Instagram followers in July 2025 by seemingly soft-launching a new relationship with a mystery man. In the clip, Kat admitted she was as a “girl whose whole life is online” before cutting to her beau’s torso and describing him as a “guy whose whole life is private.” (Her partner’s face was never shown in the video.)
The sexy video concluded with Kat playfully biting the mystery man’s ear and then pulling him into a kiss. ’s tongue-in-cheek caption read: “Perfect match? Here we go again.”
Her ex-boyfriend Tartick admitted to Instagram followers at the time that he had no idea Kat was planning to soft launch a new relationship.
“First seeing this is this Q rn,” he added. “She deserves the best in life. Truly happy for her.”
John Mayer
Kat and the ‘Your Body Is a Wonderland’ singer sparked dating rumors after they were spotted on back-to-back dates. A source later confirmed to Us Weekly that while the pair were dating they were not in a serious relationship.
“John sought her out and pursued her,” the insider revealed to Us. “Kat just broke up with someone she had been dating for a few months and thought it would be fun to date again, and was interested in John.”

However, Kat soon raised eyebrows during a Q&A when she was asked whether or not she was dating anyone.
“I already told you [that I’m single],” she insisted. “I cut all my hair off — out of the blue one day. You think I just did that for no reason? It holds memories.”
The comedian went on, “Look, at the distance between my shoulder and my hair? OK, I thought you knew me better than that. This was a cry for help … [That’s a] tell-tale sign of a relationship gone bad.”
