During Taylor Swift's show at AT&T stadium on Saturday night, Taylor walked to the edge of the stage, took the hat off her head, and handed it to a 9-year-old fan.
That fan was Selena Gomez's sister Gracie. Gracie handed something to Taylor in return, but it's not clear what it was. Some fans weren't happy saying "Nepo baby strikes again".
Gracie was there with Selena, who posted a picture and video from the show, and thanked Taylor for transporting them into, quote, "your mystical, euphoric and special world." (People)
