Taylor Swift is entering her auntie era.

Just one day after her 36th birthday, the singer of “The Fate of Ophelia” cheered on fiancé Travis Kelce at Arrowhead Stadium on December 14 with the most adorable sidekicks—soon-to-be in-laws Jason Kelce and Kylie Kelce’s daughters.

In the sweet fan footage posted to TikTok, the Grammy winner can be seen hoisting up one of the couple’s daughters in a VIP suite while watching the game between the Kansas City Chiefs and Los Angeles Chargers. With Kylie—who shares daughters Wyatt, 5, Elliotte, 4, Bennett, 2, and Finnley, 9 months, with the former Eagles player—by her side, Taylor seemed to get some early experience in the auntie department.

But this isn’t the first time that Taylor has bonded with Kylie and Jason’s little girls. Recently, she opened up about what it was like introducing the toddlers to her cats Meredith Grey, Olivia Benson, and Benjamin Button, as well as getting them to unlearn what their dad previously told them about the cuddly pets—that they’re “poisonous.”
