The sisters also rocked matching headbands during the outing.

The Anti-Hero singer's concert was the duo's last public night out, and Taylor even gave Gracie an extra special shout-out during the show!

The Rare Beauty Founder has been close friends with Taylor for over a decade, and it looks like Gracie has fit into the fold quite well!

Selena and Gracie were in attendance at The Eras Tour in Arlington, rocking folklore and Speak Now-inspired outfits, respectively.

Tay shared an adorable exchange with her bestie's young sister during her performance of 22, giving Gracie her hat while Gracie gave her friendship bracelets in return.

Despite their two decade age gap, these sisters are clearly inseparable!
