Taylor Swift and her younger brother, Austin Swift, have a tight-knit bond. While the siblings don't constantly post about each other on social media, they have shared the rare tribute to each other over the years.

Taylor Swift's brother Austin is her biggest fan, and Swifties want to know more about him after he attended Travis Kelce's Chiefs game with his sister.

The 66-year-old sat in an Arrowhead Stadium suite with the pop star and Donna Kelce during Monday night’s game as Travis’ team beat the Buccaneers.
