Taylor Swift’s younger brother, Austin Swift, might just be off the market.

Austin kept a low profile — he seemed to be dressed as Santa Claus — as he appeared alongside rumored girlfriend Sydney Ness while attending the Kansas City Chiefs game on Christmas in 2023. His sister, Taylor, and their parents, Scott and Andrea Swift, were also in attendance.

Austin has been romantically linked to Ness since September 2022, when they were first spotted holding hands during a walk around New York City. The duo have kept their relationship out of the public eye, rarely getting spotted together.

Ness did, however, attend Taylor’s iconic 4th of July celebration in July 2023. She was spotted wearing a blue bikini in a photo shared via the singer’s Instagram at the time.

While Ness’ Instagram account is full of her modeling photos, Austin barely uses social media, so there are no pictures of their rumored romance thus far.

However, the pair were seen showing Taylor some support in her new relationship when attending a separate Chiefs game in October 2023. At the time, Austin walked alongside Ness and Blake Lively as Swift entered MetLife stadium for a Chiefs game against the New York Jets.
