NFL player Travis Kelce and Taylor Swift sparked romance rumors last month in Kansas City

Jessie James Decker told Fox News Digital what advice she would give to Taylor Swift when it comes to dating an athlete, saying “it’s a different world.”

Taylor Swift’s Era’s Tour stormed MetLife Stadium in May with a three-night, sold-out run.

She was back in New Jersey Sunday night with a few of her famous friends for something a little different – to support her new boyfriend Travis Kelce as the Kansas City Chiefs played the New York Jets.

Swift was joined by her best friends Blake Lively and Ryan Reynolds, with Hugh Jackman and Sabrina Carpenter spotted hanging out in her luxury suite.

Sophie Turner, who is in a divorce battle with estranged husband Joe Jonas, was also spotted catching a few plays with her pals.

Last week, the “Welcome to New York” singer made her debut at a Chiefs game in support of the Super Bowl champ, and chatted with Kelce’s mom Donna in a private box.

Swift laughed her way through the first half of the game as Kansas City pulled ahead of the Jets.

The “Cruel Summer” powerhouse sported a black, long-sleeved shirt with blue denim shorts featuring sparkling studded rhinestones along the zipper and one pocket.

Blake showed her support for Kelce and the Chiefs as she cheered alongside her husband, Ryan Reynolds.

Swift’s friendship with Lively and Reynolds runs deep. The trio have spent summers together at Swift’s Rhode Island retreat, and in her 2020 “Folklore” album, Taylor revealed the name of Blake and Ryan’s third daughter on the track “Betty.”

She also added the names of their other two children, Inez and James, into the song.

Turner, whose in the midst of a contentious divorce with Joe Jonas, stood in the background wearing a gray tank top with sunglasses perched atop her head.

Hugh Jackman, a longtime pal of Reynolds, was also seen cheering throughout the NFL game.

“The Greatest Showman” actor recently announced his split from wife Deborra-Lee Furness after 27 years of marriage.

Kansas City Chiefs quarterback Patrick Mahomes was busy playing on the field, while his wife Brittany Mahomes welcomed Swift to her first road game with the team.

Brittany and Taylor enjoyed a night out together before the game as they stopped by Emilio’s Ballato on Saturday. The old-school Italian eatery, a favorite of Joe Jonas’, is owned by Katie Holmes’ ex-boyfriend, Emilio Vitolo.

Paul Rudd, a die-hard Kansas City Chiefs fan, walked the field with his family before the game began, but seemed to miss the Swift fan-fare.

“Queer Eye” star Antoni Porowski also caught the game from the comfort of Swift’s luxury box.

Swift previously dated British actor Joe Alwyn. The former couple reportedly first met at the MET Gala in May 2016 when she was dating DJ Calvin Harris, but kept things strictly platonic.

Harris and Swift split in June 2016 following a year-long relationship.

Swift sang her way to the top of the charts in July, earning more No. 1 albums than any woman in history with her latest re-recorded album, “Speak Now (Taylor’s Version).”

She began “The Eras Tour” in March, and is on a break from touring before a stop in Brazil next month. She’ll resume the tour in the new year with concerts scheduled around the globe, including Australia, Japan, England, Austria, and back to the US.

Swifties can catch a glimpse of “The Eras Tour” at AMC and Cinemark Theatres on Oct. 13 with the world premiere of the concert film documenting the tour.

Two weeks later on Oct. 27, Swift will release her next re-recorded album, “1989 (Taylor’s Version.)”
