A security guard was seen grabbing the fan by the arms and pushing her while saying the helmet was “not allowed”.

Not long after, Austin, 32, came over to defuse the situation. “Hey, let’s not touch people,” he scolded the guard.

Austin then addressed the fan, saying, “I’m sorry about that. It’s a very cool costume.”

The two chatted a bit more before saying, “You’re enjoying the concert. Have a good night.”

He also gave her some guitar licks, according to the video, which the TikTok user captioned: “Austin Swift saving my sister from getting kicked out of Indy (night 2).”

The situation came after Kelce, 35, made a late entrance to support his pop star girlfriend on Saturday’s show.

A source exclusively told Page Six on Monday that Taylor, 34, and her family he had no idea he was going to attend because of its football program.

“(Taylor’s mom) Andrea and Austin didn’t think Travis was going to make it,” the insider told us.

“They were shocked when it came out. It was an amazing surprise and they were glad he could be there for such an important occasion.”

The source also told Page Six that the NFL star is determined to be in the crowd like the “Blank Space” singer wrapped up the US leg of her Eras tour.

“Travis trained earlier in the day and he wasn’t even sure if he was going to make it,” the insider said.

“It was a last minute decision. Fortunately, he was able to get out of training in time and show up.”

The 14-time Grammy winner returned the favor Monday as she cheered on the Chiefs in their win over the Tampa Bay Buccaneers at Arrowhead Stadium.

She showed her loyalty to the home team in a vintage leather Chiefs varsity jacketdenim shorts and black Christian Louboutin cowboy boots.

At one point, Taylor was spotted joyfully celebrating a touchdown with her mother, Andrea, and Travis’ mother, Donna Kelce.
