PITTSBURGH (KDKA) – Saturday night Heinz Field will become the center of excitement for Taylor Swift fans.

But before the concert even started, the parking lot became the scene of another big event for some Swift tailgaters.

About 40 dancers from Pennsylvania and Ohio in a flash mob helped Brad Haas propose to his girlfriend Steph Benson.

The sweet surprise was caught on camera as everyone danced to a mix of songs, including “Leave the Night On” by Sam Hunt and “Sparks Fly” by Taylor Swift, outside of Gate A at Heinz Field.

When the dancers were done, Brad grabbed his girlfriend by the hand and proposed to her in front of dozens of people — and of course she said YES!
