Taylor Swift's Football Game Behavior With Brother-In-Law Jason Proves She's Officially A Kelce

Taylor Swift appears to be adjusting easily into married life to NFL star Travis Kelce. And based on these side-by-side pics showing Taylor Swift's confident gameday evolution, the "You Belong With Me" hitmaker is as content as can be. What's more, the chart-topping pop star seems to be getting along very well with her husband's family, and an interaction during a September 14, 2026 game between the Kansas City Chiefs and the Denver Broncos solidified Swift's place as an official Kelce.

Based on this clip posted to X, Swift could be seen viewing the game alongside her brother-in-law, Jason Kelce, who is a former NFL athlete himself. The "Love Story" singer was clearly elated, cheering with everyone else while grabbing Jason Kelce's arm, before slapping her hands against his chest in her excitement. It's clear that based on this interaction, Swift feels comfortable with her husband's family and has been warmly welcomed by the Kelces, with the 14-time Grammy winner also seen attending several games with her mother-in-law, Donna Kelce. 

It's safe to say that Taylor Swift has Donna Kelce's stamp of approval. Donna has been pictured alongside the "Shake It Off" singer many times since Swift and Kelce officially started dating back in 2023. And Donna Kelce has only good things to say about Swift, from praising her work and career to gushing about her character. "She is a sweetheart," Donna Kelce revealed back in June 2026 (per InStyle), showing Swift's undeniable new status as a valued part of the family.

Other Kelce members who have welcomed Swift with open arms are none other than Jason Kelce's daughters — Wyatt, Elliotte, Bennett, and Finnley. Things were awkward at first, most likely due to the sheer star power of Swift's name, with Jason Kelce himself commenting on a segment of the Jason and Travis' "New Heights" podcast (per People), "When they had to meet Aunt Tay Tay, they were calling her 'Taylor Swift.'" While Travis found this "adorable," Jason explained he told the girls to simply call her "Taylor." Swift is now closer than ever with her nieces, proving that being accepted by the Kelce family is part of the science behind Taylor Swift's winning relationship with Travis Kelce.
