Taylor Swift does THIS to Selena Gomez's Sister Gracie Mid-Concert

Taylor Swift does this to win hearts.

Taylor Swift gave her Arlington, Texas fans a night to remember on Saturday as she continued her long-awaited Eras Tour. And one fan, in particular, was given something special to take home!

Swift greeted Selena Gomez's little sister Gracie Elliott Teefey at the edge of the stage's catwalk and handed her the hat off her head during her performance of her Red blockbuster "22." Fans at the show caught the touching moment, which even shows the 9-year-old hand Swift something in return.

Gracie can be seen in the video wearing a purple dress evocative of Swift's Speak Now era, while she waits for the star, who walks down the catwalk holding a hat. In response, Gracie gave Swift a friendship bracelet, which made the singer smile.

Taylor Swift and Selena Gomez's friendship

Swift's adorable concert encounter comes just weeks after she officially began her tour in Glendale, Arizona. While many celebrities have come out to support the Grammy winner, her close buddy Gomez was as supportive as ever last night.

In another fan-filmed video, Gomez applauded Swift throughout the night while wearing a cardigan from Swift's merchandise and standing behind her half-sister.

Outside of supporting one other on tour, Gomez and Swift have a lengthy history of friendship that began while they were both dating a Jonas sibling in 2008. They've exchanged music video appearances, lovely birthday celebrations, posts promoting one other's albums, and instances where they cheered each other on in award show audiences since then.
