Kat Stickler has stirred up speculation about a new romance with John Mayer after she was spotted donning his official merchandise while enjoying donuts in bed, prompting fans to take notice.

Astute followers of Stickler, aged 31, observed her subtle nod to Mayer, 48, when she posted an Instagram Story earlier this month, seemingly showing her support for the musician and his brand.

The image, which was shared on DeuxMoi’s Instagram page on Friday, November 28, features Stickler clad in Mayer’s “Life With John Mayer Baby Blue Sweatpants,” available on his official website.

Adding to the intrigue, the comedian also included a reference to Mayer’s well-known fondness for donuts, as she relaxed in bed next to a box of the sugary delights. Mayer, as fans may know, is famous for his “Donut Sundays” tradition, which he has embraced during his tours.

Rumors are swirling that John Mayer and Kat Stickler are indeed dating and enjoying each other’s company after their initial connection online. An insider revealed to Us Weekly, “John reached out to her and showed interest. Kat had just ended a relationship with someone she had been seeing for a few months and was open to dating again, thinking it would be fun.”

Stickler’s social media post came more than one month after Us Weekly confirmed that she and Mayer are dating after crossing paths online.

“John sought her out and pursued her,” a source exclusively told Us on October 13. “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.”

The insider noted that the “Your Body is a Wonderland” singer’s relationship with Stickler is “still very new” but the pair have been out together on several occasions.

“He has been actively pursuing her, inviting her places and texting her often,” the source added. “She is interested and seeing where it goes.”

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.” […]

Mayer and Stickler were first linked after being spotted dining together at New York City’s Fly Fish earlier that month.

While the insider told Us that Stickler “doesn’t think this will be a serious relationship,” the source said she is “having fun” with the musician.

Neither Stickler nor Mayer have publicly confirmed their relationship status but Us Weekly has reached out for comment.

The twosome have continued to spend time together amid their casual romance, including another NYC sighting earlier this month.

Mayer was spotted with Stickler on November 1 at NYC’s Torrisi, according to DeuxMoi.

The next day, the “Gravity” singer was seen in Manhattan’s West Village with longtime friend Andy Cohen and a woman who appeared to be Stickler, per a TikTok video.

Stickler’s budding relationship with Mayer comes after she confirmed in October that she was fresh off a breakup following a romance with a “mystery man” that began over the summer.

Stickler gave fans a glimpse at her elusive boyfriend in July after splitting from Bachelor Nation’s Jason Tartick in October 2024. (Kat was married to Mike Stickler — with whom she shares daughter MK — prior to her romance with Tartick.)

Katy Perry and John Mayer recently had an unexpected run-in in Los Angeles. Perry, 40, and Mayer, 47, were spotted at Sabrina Carpenter’s Short n’ Sweet Tour show at the Kia Forum in Los Angeles on Sunday, November 17. According to a video shared by DeuxMoi, the exes were sitting in the VIP section together. […]

“Girl whose whole life is online,” Kat wrote via an Instagram video in July showing her shaking the hand of her new man before the camera panned to his torso. “Guy whose whole life is private.”

Over the next few months, the influencer gave her followers a few more looks at her boyfriend, but never shared details about his identity.

Shortly after she was spotted with Mayer in early October, Kat confirmed she and the mystery man had broken up. She joked via an October 14 social media video that her new haircut — a bob — was a “tell-tale sign of a relationship gone bad.”

“When a haircut is never JUST a haircut,” Kat captioned the video. “Chopped the hair, kept the peace.”

His most-recent public relationship was with Katy Perry, whom he dated on and off from 2012 to 2015.

Two years after their split, Mayer revealed that his song called “Still Feel Like Your Man” was about Perry, 41.

“Who else would I be thinking about?” Mayer told The New York Times at the time. “And by the way, it’s a testament to the fact that I have not dated a lot of people in the last five, six years. That was my only relationship. So it’s like, give me this, people.”
