Taylor Swift apparently rescued some of her concert attendees from a security guard who had "Bad Blood."

The pop star performed for a second night at Lincoln Financial Field in Philadelphia Saturday (May 13).

During an ironic performance of "Bad Blood," Swift seemingly noticed a fan being yelled at by a security guard. The fan was, according to multiple fan accounts, too close to the barricade for the staff member's liking.

Without missing a beat, and singing along to the tune of the song, Swift furrowed her brow, pointed at the security guard and scream-singed, "Hey, stop!" and "She wasn't doing anything!"

On TikTok user posted a video of the moment and thanked the "Lover" singer for taking action.

"Hey [Taylor Swift] ... THANK YOU from all of us on the floor for yelling at that security guard. He was a pain in the a-s the entire night and the fact that this happened during #badblood made it even better ... P.S. [the] show was PHENOMENAL," the TikTok user captioned the video.

In a comment, the TikTok user claimed that the guard was "giving a girl s--t for 'being too close' to the barricade" and being too strict and unfriendly with fans all night.

The security guard was reportedly pulled away by other staff members following the interaction with Swift.

Another TikTok user claimed she was one of the women harassed by the security guard at the concert.

She said she and her friends were gifted free tickets to the tour's third Philadelphia show for the following night after the ordeal.

Swifties went off in the comments on TikTok.

Some dubbed Swift's updated lyrics and performance as "Bad Blood (Security Guard Version) (Taylor's Angry Version) (From The Tour)."

"'I got fired cause Taylor Swift yelled at me; not sure if that’s a win or what," one fan comments.

"Are we all gonna yell 'She wasn’t doing anything' and 'Hey stop' during 'Bad Blood' now because that would be great," another joked.
