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

Taylor Swift is making dreams come true.

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.

Abbi Williams, a foster mother, shared photos of the experience on Instagram, including photos of her children alongside her friend’s foster children smiling in a group photo with Swift, as well as holding up autographed covers of Reputation.

“A night my girls and I will always remember – meeting Taylor Swift!! Thank you for such a generous evening with your littlest fans. Your show is amazing – you and your team did an incredible job!!” she wrote in the caption, adding the hashtags, “#taylorswift#reputationtour #goseeit #fosterkids#concert #heartofgold @gymnastmaddi@izzibgrace.”

Another mother, going by the name Momma Bear on Instagram, also shared photos of her foster children, writing, “When @taylorswift invites you to her final dress rehearsal, you go. We couldn’t bring cameras in, just know that if you are able to see her #reputationstadiumtour DO IT! She was such a gracious and generous hostess…complete with a pizza party and photo op afterward.

She continued, “The munchkins wrote thank you cards to Miss Swift and I was blessed to be able to give them to her kind daddy who promised to bring them to her before the show. He gave a TS guitar pic to each of the kids. .”

She also shared more details of the experience on her Instagram Story, saying the singer was “amazing.”
