Kat Stickler's Dating History From Mike to Mayer

The social media personality and humorist Kat Stickler frequently leaves her audience wondering about her romantic relationships.

This TikTok celebrity gained widespread recognition during the global health crisis with her spouse, Mike Stickler, by sharing family-oriented videos. Nevertheless, the couple ended their personal and professional partnership shortly thereafter, in early 2021. (Mike and Kat share a daughter named Mary-Katherine, often called MK.)

Following her separation, Kat was in a relationship with Bachelor franchise personality Jason Tartick for five months in 2024, cultivating a significant fan base through their charming videos as a couple. Much to the astonishment of many followers, Kat and Tartick broke up in October 2024, and subsequently, she was connected romantically to musician John Mayer.

“Things simply didn't pan out … I'd rather not discuss it,” Stickler conveyed to her TikTok audience regarding her breakup with Tartick. “I realize that when a relationship is shared publicly, this subsequent phase, the fallout, must also be revealed — Hooray, how delightful I find this!”

She continued, “However, I simply wanted to inform you all that the affection wasn't in vain. I believe it’s often simple to assume that when a partnership concludes, the feelings shared were purposeless. Yet, love is never without purpose. Therefore, that is my complete statement.”

Mike Stickler

During the COVID-19 health crisis, Kat created TikTok content featuring herself and her spouse often executing playful tricks with their child, MK. Within these videos, the pair revealed their engagement, subsequent marriage, and the news of expecting MK, all occurring within a three-month span in 2019.

When followers observed in early 2021 that Kat was predominantly sharing individual content on their shared account, she and Mike collaborated on a video to discuss speculation about their separation.

“Regrettably, [the gossip] holds truth,” she clarified to her audience. “We are parting ways. We simply desired to be forthright with you all, as you have been with us since the outset of this entire experience.”

Mike asserted that Kat bore “no blame whatsoever for any of this,” further stating: “I have numerous aspects of my personal life that require attention.”

Four years following their separation, Kat responded forcefully to assumptions and disapproval regarding her romantic endeavors after her divorce.

“I have experienced two significant relationships since my divorce, which occurred half a decade ago,” Kat highlighted on Instagram. “If public opinion truly mattered to me, a) I likely wouldn’t pursue this profession. And b) I would most likely still be married!”

Cameron Walker

Among the two significant relationships Kat seemingly referenced in her 2025 rebuttal was her nine-month romance with Walker, spanning from December 2021 to August 2022.

Kat subsequently informed her online audience that her relationship with Walker didn't succeed as she had entered a new partnership too swiftly after her divorce from Mike.

Jason Tartick

Kat encountered and connected with the former Bachelor participant when appearing as a guest on his podcast, “Trading Secrets,” in April 2024. After the two made their relationship “Instagram Official” in June 2024, Kat and Tartick rapidly gained popularity as a beloved online duo.

Admirers eagerly kept up as the couple chronicled significant life events — such as Tartick introducing Kat to his mother and father — through social media platforms. Regrettably, Tartick surprised followers in October 2024 by announcing that he and Kat had ended their relationship.

“It grieves me to inform you that Kat and I are no longer a couple,” Tartick posted on his Instagram Story. “It's accurate to state that I love intensely and become deeply invested quickly. Occasionally in life, that succeeds, and at other times, it does not. On this occasion, it did not.”

Tartick commented again when his audience theorized that the separation might have been staged for one of their widely circulated prank clips.

“It was entirely authentic. It occurred rapidly, it transpired swiftly,” Tartick conveyed to his “Trading Secrets” podcast audience. “It was unforeseen and that proved exceptionally challenging.”

Kat issued her own statement when individuals criticized her choice to introduce her young daughter, MK, to Tartick so early in their romance. The internet personality verified that her former partner — whose name she omitted from the message — had spent time with MK, and that her child also encountered Stickler’s “male acquaintances” and “the spouses of my female friends.”

“Firstly, she is consistently present with me when these men are brought into her existence, and they are invariably presented as mommy's companions,” Stickler asserted. “She does not address anyone as 'dad.' She possesses a father [and] that is never a source of bewilderment for her, and I assure you all, she is fine.”

She continued, “My sole hope is that MK understands I am striving to locate the appropriate companion for both of us, as we come as a complete unit. And while I acknowledge I don't always make impeccable choices, I gain insight from my errors, and every choice I do make stems from what I believe is most beneficial for my daughter and me.”

Mystery Man

Kat captivated Instagram users in July 2025 by apparently subtly revealing a new romance with an unidentified individual. In the footage, Kat acknowledged herself as a “woman whose entire existence is public on the internet” before transitioning to her partner's upper body and characterizing him as a “man whose entire existence is personal.” (Her companion's face was not displayed in the video.)

The alluring video concluded with Kat playfully nipping the unknown man's ear before drawing him into an embrace. The accompanying caption, offered with a touch of irony, stated: “An ideal pairing? Starting over.”

Her former boyfriend, Tartick, confessed to his Instagram audience at that time that he was unaware of Kat's intention to subtly unveil a new romantic connection.

“My initial reaction upon seeing this is this very moment,” he further remarked. “She merits absolute happiness in life. I am genuinely pleased for her.”

John Mayer

Kat and the vocalist of ‘Your Body Is a Wonderland’ ignited speculation about a romance after being seen on consecutive outings. An informant subsequently affirmed to Us Weekly that although the duo was seeing each other, their connection was not profound.

“John actively sought her attention and pursued her,” the confidential source disclosed to Us. “Kat had recently ended a multi-month relationship and considered it enjoyable to engage in dating once more, and found John appealing.”

The Moment Jason Tartick Realized His Relationship with Kat Stickler Was Unviable

Nevertheless, Kat soon caused bewilderment during a question-and-answer session when queried about her current dating status.

“I've already informed you [that I am unattached],” she maintained. “I spontaneously cut off all my hair one day. Do you honestly believe I did that without cause? It encapsulates recollections.”

The humorist continued, “Observe the length between my shoulder and my tresses? Fine, I believed you understood me more intimately. This represented an appeal for assistance … [That is a] clear indicator of a romance deteriorating.”
