Taylor Swift is making dreams come true. Watch as She Treats These Foster Kids to Private Concert & Pizza Party ‘They’ll Never Forget’…

The “Delicate” singer, 28, met her “littlest fans” — foster children from Arizona — on Saturday when she invited more than 2000 special guests to her final dress rehearsal of her upcoming Reputation Stadium Tour.

An attendee tells PEOPLE Swift spoke to the crowd of excited children and foster parents before the show and asked if it was their first time attending a concert. About 500 hands flew into the air, the concertgoer says.
