Taylor Swift fans think they know everything about the Eras singer – from her Easter egg clues to her relationship history to her cat’s middle names. However, recently, Swifties were left completely stunned after discovering that Taylor has a younger brother.
Yes, it turns out, the Grammy-winning pop icon isn’t an only child after all.
Meet Austin Swift – The ‘Secret’ Swift Sibling.
Austin Swift is Taylor’s younger brother. He was born in March 1992, three years after Taylor was born, making him 33 years old now. While Taylor is the megastar performer we see on stage, Austin has built a successful career as a businessman, producer, and actor.
He also plays a vital role in Taylor’s empire behind the scenes, managing parts of her music licensing. However, despite their strong bond, many fans were unaware of his existence until a recent viral moment.
The Viral Moment That Left Fans Shocked

Earlier this week, a Reddit post took off after Austin was photographed bumping into actress Natalie Portman on the streets of Tribeca, New York City.

In the photos, Austin is seen dressed casually in a checked shirt, smiling widely as he greeted Natalie, who was laughing with her back to the camera. While some fans questioned how Austin and Natalie knew each other, most were distracted by something else entirely.
“Taylor has a brother? I must have been living under a rock,” one person wrote on Reddit.
Another added, “Didn’t even know she had a brother until now.”
A third said, “She gives off only child vibes lol.”
Someone else commented, “That is Taylor Swift’s brother? Who knew!”
It’s surprising considering Austin has appeared at public events with Taylor countless times, including major award shows like the Country Music Awards and the Golden Globes.

They’re Super Close
Taylor and Austin share a very close sibling bond. In 2020, Taylor posted a heartfelt tribute on Instagram for National Sibling Day, calling Austin one of her “best pals” along with some sweet photos of them together.

While supporting his famous sister behind the scenes, Austin Swift is making a name for himself on the big screen. He made his film debut in 2016 alongside Pierce Brosnan in the thriller I.T., and that same year, he appeared in Ben Affleck’s action drama Live By Night. Since then, Austin has continued building his acting résumé with roles in the 2019 comedy-drama Breaking for Whales, starring opposite Harry Potter’s Tom Felton, and the horror thriller We Summon the Darkness, featuring White Lotus actress Alexandra Daddario. Beyond acting, he has also appeared in some of Taylor’s music videos, including “Christmas Tree Farm” and “The Best Day,” the latter showcasing treasured family archive footage.

The Time He Protected A Fan During The Eras Tour
Austin Swift, Who’s Protective of Taylor’s Fans, Stepped In When Security Got Too Rough
During one of Taylor’s Eras Tour concerts at Lucas Oil Stadium in Indiana last year, a die-hard fan almost got kicked out by security for wearing a Travis Kelce costume. The fan, who wore a Kansas City Chiefs jersey, helmet, and football gloves, attempted to draw Travis’s attention in the VIP section.
But security stopped her and attempted to escort her out, saying the helmet was “not allowed.”
That’s when Austin stepped in.
A TikTok video captured him telling the security guard:
“Hey, let’s not put hands on people.”
Another person nearby added, “Guys, let’s just calm down a little bit, cause her family is here, alright? That was a little aggressive.”
Austin then smiled at the fan, praised her outfit, and wished her a great night at the concert.
“I’m sorry about that. It’s a cool costume,” he said before walking away.
Fans React To The Surprise Discovery
Now, after seeing the photos of Austin and Natalie Portman, Swifties can’t stop talking about them online.
Some say they feel like “bad fans” for never knowing Taylor had a brother. Others admitted they thought she was an only child because of her fiercely independent vibe.
However, those who have followed Taylor closely over the years know that Austin has always been by her side, quietly supporting her every step of the way without seeking fame for himself.

Now Everyone Knows the Truth About Their Bond
He’s a producer, actor, businessman, and most importantly, Taylor Swift’s little brother and trusted friend.
He prefers to stay out of the spotlight, but his love and loyalty to his sister are evident for all to see – whether it’s on the red carpet, backstage at her tours, or standing up for fans when they need him.
So next time you watch a Taylor Swift performance or see her on an award show stage, remember – there’s a supportive brother somewhere in the crowd, cheering her on just like the rest of us.
