Selena Gomez and her younger sister Gracie dressed up as Taylor Swift as they attended the Eras Tour in Arlington, Texas, on Saturday.

The Only Murders In The Building actress, 30, donned a Folklore-reminiscent look while her nine-year-old sister Gracie channeled the singer’s Speak Now era in a bright blue halter dress.

The Disney alumna’s father was also spotted in a ‘Proud Swiftie Dad’ T-shirt alongside the two half-sisters.

Together, the trio enjoyed the 33-year-old singer–songwriter’s second concert of her three-night run at the AT&T Stadium.

The Lose You to Love Me singer — who is currently rumored to be romancing former One Direction member Zayn Malik —  donned a cream knit and rocked curly bangs, as Taylor did in her Cardigan music video.

Underneath the black-trimmed and off-white cardigan, the Spring Breakers star modeled a flowing white negligée gown.

The Rare Beauty founder wore her dark brunette tresses in a sleek, low bun and styled her curtain bangs in face-framing curls.

The look seemingly paid homage to her longtime friend’s 2020 hit single from her eighth studio album Folklore.

At her side, Gracie was spotted in a purple–blue halter gown similar to the one Swift sported during her Speak Now World Tour in 2011 and 2012.

Selena’s younger sister also donned a pair of heart-shaped sunglasses, which looked nearly identical to a pair Taylor wore in the music video for her song, 22.

And while performing the 2012 pop hit from her Red album, Taylor even walked to the end of the stage and took the hat off her head to give to Gracie.

In the adorable moment, Gracie was reportedly also spotted giving Taylor a friendship bracelet in exchange.

According to fans, Selena’s father — Ricardo Joel Gomez — was also spotted at the concert with the sister duo.

Fans reported seeing him also showing his support by wearing a black T-shirt with the words ‘Proud Swiftie Dad’ emblazoned across the torso.

The day after, Selena took to Instagram to share a photo of Gracie holding up a heart with her hands while standing in the crowd of concertgoers.

‘Thank you bestie for having me and my sissy transport into your mystical, euphoric and special world,’ she wrote in her caption.

‘Proud to know you! Love you forever and always,’ she said, addressing the musician.

As part of her whopping 44-song setlist, Taylor also surprises her fans at every performance with surprise songs — different for each concert.

Saturday’s concert was no different, as she performed Cruel Summer from her seventh studio album, Lover.

Concert attendees reportedly captured Selena singing and dancing along to the hit with her little sister in her Folklore look.

During record-breaking concert lengths, Taylor entertained fans as she showed off her extravagant wardrobe that took hundreds of hours to make. One particular gown even involved upwards of 200,000 crystals in just a single costume.

The Pennsylvania-born star had not embarked on a tour since 2018. In the past five years, she has released four new studio albums as well as re-recorded several of her older works.

Because of the pandemic, she was unable to perform music from her Lover, Folklore, and Evermore albums and now is using the Eras Tour to do so.

In addition, she is also performing music from her latest album, Midnights — which was released in October 2022.
