In an interview with People, the 8-year-old’s mom, Jessica Piazza, said that the unbelievable moment at Highmark Stadium in Orchard Park, N.Y., Sunday has left her daughter “in shock.”

Ella sat in shock the remainder of the game, and I was also so excited about the interaction as a Swiftie myself,” she said, adding that she was overjoyed that her “daughter’s dream just came true!”

Piazza told the outlet that the special moment almost didn’t happen as the family was originally sitting across the stadium away from the VIP suite that Kelce, 36, and the “Bad Blood” were in.

Luckily, Piazza’s friend knew someone who was sitting below the Kelce family suite and they offered to switch seats with Ella and her mom during the game so the Grammy winner could see her sign, which read: “Buffalo Bills + Taylor Swift = Best First Game Ever.”
