😲 Taylor Swift has a HIDDEN family member?! Fans are losing it after a bombshell reveal about someone close to the pop queen they never knew existed! Who’s this mystery Swiftie?

Taylor Swift fans have been left shocked after learning that the Eras singer has a younger brother… even though they’ve been seen together countless times.

Businessman and producer Austin Swift, 33, was born in March 1992, three years after the Grammy award-winning artist, 35, and manages elements of his sister’s music licensing.

But earlier this week, a Reddit post sparked a huge response after he was pictured running into actress Natalie Portman while walking through Tribeca, New York City.

Austin, dressed in a checked shirt, was seen grinning in the pictures, as Black Swan actress Natalie, 44, laughed with her back to the camera.

While some social media users questioned how the pair became acquainted, other dumbfounded fans expressed their surprise that Taylor isn’t an only child.

In a thread discussing Austin and Natalie’s unexpected run in, one commented: ‘Didn’t even know she had a brother until now.’

‘Taylor has a brother?’ another asked. ‘I must have been living under a rock.’

‘How did I not know she has brother?’ said a third.

Another wrote: ‘She def gives off only child vibes lol.’

A fifth added: ‘I wouldn’t recognize this man out of a line up of one. Well done Mr. Swift.’

‘That is Taylor Swift’s brother? Who knew!’ someone else shared.

Despite the confusion, Austin and Taylor have appeared together at a number of events over the years, including the Country Music Awards and The Golden Globes.

In 2020, Taylor described her brother as one of her ‘best pals’ as she paid tribute to him on National Sibling Day.

Besides working with his famous sister, Austin has also worked as an actor both on the big and small screen.

For his film debut in 2016, he starred opposite Pierce Brosnan in the thriller I.T. That same year, Austin appeared in Ben Affleck’s action drama, Live By Night.

In 2019, Austin starred alongside Harry Potter alum Tom Felton in the comedy drama Braking for Whales.

Also in 2019, he appeared in the horror thriller film, We Summon the Darkness, which starred White Lotus actress Alexandra Daddario.

Additionally, Austin has appeared in archive footage in Taylor’s music videos, including Christmas Tree Farm and The Best Day.

In November 2024, Taylor’s brother came to the rescue when security guards at LucasOil Stadium in Indiana attempted to kick a fan out for dressing up as Travis Kelce.

During one of the pop star’s Eras Tour concerts, a die hard fan approached the VIP section, trying to grab the Kansas City Chiefs star’s attention.

A video posted on TikTok showed the fan wearing a Travis jersey, helmet, and football gloves as she approached the area only to be stopped by security.

One staff member grabbed the fan by the arm and directed her the other way, saying the helmet was ‘not allowed.’ Austin then walked over to diffuse the situation.

‘Hey, let’s not put hands on people,’ he scolded the guard.

Another person in the background could be heard saying ‘Guys, let’s just calm down a little bit cause her family is here, alright? That was a little aggressive.’

After intervening, Austin chatted with the fan and commended her outfit.

‘I’m sorry about that. It’s a really cool costume,’ he said. ‘You guys enjoy the concert. Have a great night.’
