Swift and Kansas City Chiefs tight end Travis Kelce started dating over the summer, and their relationship appeared to be going strong Sunday in Foxborough. Swifties left Gillette Stadium happy on Sunday after the popstar was in attendance for the Patriots-Chiefs game in Foxboro.

Plenty of fans were at Gillette Stadium on Sunday hoping to get a glimpse of Taylor Swift cheering on her boyfriend as the New England Patriots hosted the Kansas City Chiefs.

Their wish was granted as the popstar arrived in Foxborough, Massachusetts, a little before kickoff, then sat in one of Gillette's boxes. Also with her was musician and actress Alana Haim.

A poster of Swift in a Gillette Stadium tunnel even turned Kelce's head before the game began.

It was a great day for Chiefs fans and Swifties, many of whom said they were only at the game hoping for a glimpse of Swift.

"We have our binoculars. We're just trying to see Taylor," Kara May, of Needham, said.

Seeing Swift at Gillette under these circumstances was a lot more affordable than her Eras Tour this past summer.

Not everyone was thrilled to see the singer, however.

"Taylor Swift is ruining football," 10-year-old Jordan Sisum said. "We're here for football, not Taylor Swift."

Other fans were at the game for both -- Swift and football.

"We're not doing very well this year so it's been tough to pay the money to come to the game but we're here for Taylor, Swift, and Bill Belichick," Canton resident Julia Kent said.

Like Swift, Bill Belichick has been in the spotlight recently -- though in a very different way, with a 3-11 record.

His future with the Patriots has been a hot topic in New England, but many still point to the fact that he's won six Super Bowls with the team.

Drama aside, there's no arguing that Taylor Swift's new love for football, is attracting her fans to become football fans.. bringing a lot of money to the NFL. Live outside Gillette Stadium, EL NBC 10 Boston
