David Harbour Reveals Taylor Swift Sent His Stepdaughter a "Handwritten Letter" at the Eras Tour

Swift's longtime pal Gomez brought her then-9-year-old little sister to a tour stop in Arlington, TX, on April 1, and both seemed to have the time of their lives. At one point, Swift even stopped to give her fedora to Teefey during a performance of "2022," per People, while Gomez was spotted wearing a cardigan from Swift's merch line.

"Thank you bestie for having me and my sissy transport into your mystical, euphoric and special world," Gomez wrote in an April 2 post. "Proud to know you! love you forever and always."
