Even Taylor Swift isn’t immune to eldest daughter syndrome. With the news of Swift’s engagement to Travis Kelce, it’s entirely possible that the chorus (which includes lines like “I’m never gonna break that vow / I’m nеver gonna leave you now, now, now”) may have been written with wedding bells in mind. Swift herself is the eldest child of her family; she has one younger brother, 33-year-old Austin Swift. “Rather than send lawyers or management, I sent my mom and my brother, who I work with, to L.A. They told them the whole story.”Austin also previously made a rare comment on Swift’s career during a 2017 interview with Vanity Fair.
