Eras Tour concert tickets, not only has the die-hard “Swiftie” been looking forward to seeing the pop superstar perform live — she’s had her fingers crossed that she gets the opportunity to meet her idol in person.“I’m going to yell and scream and jump up and down. I’m so excited to see her!” the elated tween, who has Down Syndrome, told The Post in anticipation of attending Swift’s concerts on Friday and Sunday at MetLife Stadium. At the DelVecchio home in Westchester, T-Swizzle’s tunes are blasted from the minute Grace wakes up until bedtime, said her mom, Theresa DelVecchio. On Saturdays, the family has a tradition of serving up “folklore pancakes” – which are just regular pancakes, but cooked while Swift’s “Folklore” album plays in the background, Theresa said.“[Grace] plays the Taylor Swift playlist on Alexa 24/7 — her older brother is like, ‘Enough already!’” Theresa said with a laugh.
