Not only did Tay's show bring on a random marriage proposal Saturday night, but also a surprise duet from Little Big Town. As if them all singing "Pontoon" together on stage wasn't cool enough, Taylor also busted out LBT's song "Girl Crush" with her famous pals backstage before the show, too.
Taylor posted photos of her hangout with fellow singers Kelsea Ballerini, Vance Joy and Rachel Platten, too. "Petition for 'Yeah Boy' to be @kelseaballerini's next single because it is MY EVERYTHING," Tay captioned one Instagram video of them singing Kelsea's song.
She also hung out with Dance Moms star Maddie Ziegler, who was totally excited about meeting T-Swift again. She posted their pic on her Instagram page.
Dave Matthews Band was the other big act taking over the 'Burgh that night. Too bad he didn't pop up on stage with Tay. Now that would've been an even more epic homecoming!
