PITTSBURGH (KDKA) – Taylor Swift rocked Heinz Field Saturday night.

Thousands of her biggest fans packed the stadium for her 1989 world tour.

It was her third performance in Pittsburgh – she took the stage around dusk.

Before the concert, the parking lot was also the scene of a big event.

About 40 dances in a flash mob helped Brad Haas proposed to his girlfriend Steph Benson. The sweet surprise was caught on camera. Watch here.

And Taylor Swift wasn’t the only big act in town this weekend.

Dave Matthews Band was at First Niagara Pavilion in Burgettstown Saturday night.

Later this summer, The Rolling Stones will also play Heinz Field June 20 and One Direction will perform Aug. 2 at the stadium.
