Kansas City Chiefs

Taylor Swift gave security at Arrowhead Stadium a crash course in good manners on Sunday, telling one guard to speak a little nicer to the paparazzi.

The pop superstar arrived at the stadium in Kansas City to watch her boyfriend, Travis Kelce, and his K.C. Chiefs battle the Denver Broncos on the field — but Taylor had her own itty-bitty skirmish behind the scenes before the kickoff.

Check out the video ... Taylor was being chauffeured in a golf cart through the arena with her mom and dad -- Andrea and Scott.

Taylor Swift's ready to watch her man take care of business against the Denver Broncos ... pulling up to his Sunday afternoon game in K.C. in a biz-casual ensemble.

The singer-songwriter rolled into Arrowhead Stadium in a red and black checkered blazer, pulled over a low-cut black top ... with a tiny skirt matching her jacket.

Clearly, she's in her "No-Nonsense Era" ... preparing to watch her boyfriend Travis Kelce's team beat up on their division rival.

Travis Kelce is used to taking hits on the field ... but he was blindsided by a blow off of it this week -- when "Jeopardy!" ribbed him with one of its clues!!!

The game show fired off the diss when a contestant asked to receive a hint from a category titled, "The TV Show In Question."

The $200 clue -- which host Ken Jennings read out loud -- stated, "'Are You Smarter Than a Celebrity?' is hosted by this man who's maybe more famous as a BF than as a 3-time Super Bowl Champ."

While Jason Kelce has expressed remorse over his actions during a viral confrontation with a "fan" in Happy Valley last weekend, Penn State cops still have not been able to ID the man who started the altercation with the retired NFL star.

A spokesperson for the university police department tells TMZ Sports that they do not know the identity of the guy, adding no one has come forward to make a complaint over their personal property (smashed phone) being damaged.

FYI, an officer who observed some of the incident did file a report.

Travis Kelce is sticking up for his older bro after his recent blowup on a spectator at the Penn State game -- saying he knows Jason has no hate in his heart.

The Kelce bros kicked off their latest episode of their "New Heights" podcast by addressing the elephant in the room ... with the Philadelphia Eagles legend once again expressing his regret over entertaining the heckler -- especially returning homophobic language hurled at him in the altercation.

The Kansas City Chiefs superstar then spoke on the situation ... saying he knows the magnitude of it all is taking a toll on Jason -- but he feels like it isn't as big of a deal as it's been made out to be.

Taylor Swift's brother, Austin, took swift action to protect one excited fan from a combative security guard ... intervening before someone emerged as the "Anti-Hero."

During the singer's "Eras" tour stop in Indianapolis over the weekend, a fan wearing a Travis Kelce costume tried to get the attention of the Kansas City Chiefs tight end ... who popped up in the VIP section of the stadium to cheer on his superstar girlfriend.

As the passionate Swiftie -- who donned a full NFL getup, helmet and all -- tried to get Travis to look over at her, the guard grabbed her by the elbow and began guiding her away from the floor.

The viral headstand celebration has taken the NFL by storm ... and New York Giants legend Eli Manning was the latest to get in on the fun -- hitting the move after the Chiefs secured a game-winning touchdown on "Monday Night Football."

The crazy celly first made waves during a college football game in Texas ... when a wide receiver on the Incarnate Cardinals propped up on his head after hauling in a deep touchdown pass.

Fast forward to NFL Sunday ... and the likes of Amon-Ra St. Brown and Drake London did their own versions of the celebration after they found the end zone in their respective games.

Patrick Mahomes' mom is making it clear who she's voting for in Tuesday's presidential election ... she rocked a MAGA hat to her son's game -- and shared a very pro-Trump message to go along with it.

Randi Mahomes pulled up to Arrowhead Stadium for Patrick's "Monday Night Football" tilt with the Tampa Bay Buccaneers ... donning a Chiefs sweatshirt, some light blue jeans and a red "Make America Great Again" hat.

Once she got into her suite seats -- she filmed a video message in the get-up ... making it known she's hoping Donald Trump beats Kamala Harris this week.

Taylor Swift is back at her home away from home ... Arrowhead Stadium in Kansas City ... and she's ready to watch Travis Kelce ball out on Monday Night Football.

The singer is in the house to watch the Kansas City Chiefs take on the Tampa Bay Buccaneers ... she just arrived, wearing a mostly all-black outfit ... with a matching top, shorts and knee-high boots.

Taylor topped off her look with a Chiefs jacket ... and, she looks ready to cheer on her man as the Chiefs look to remain the only unbeaten team in the NFL.

Matthew Stafford's wife says she loves Taylor Swift, but initially wasn't too happy with the pop superstar crossing over into her world ... admitting the NFL's coverage of Travis Kelce's romance made her "jealous."

Kelly Stafford weighed in on the topic on her "The Morning After" podcast ... when she made it clear her issue wasn't with Swift at all, but more so how her relationship with the Kansas City Chiefs superstar was attracting a ton of buzz.

"I will say I kind of got tired of the Chiefs’ coverage of it, actually the NFL’s coverage, of this budding relationship last year," Stafford said. "And can she do anything about that? No, she can’t."

Patrick and Brittany Mahomes are leading the charge to get a WNBA team in Kansas City ... and the Chiefs superstar explained his reasoning behind the pursuit on Thursday -- calling it a "no-brainer."

The Super Bowl-winning quarterback confirmed his plans to bring a women's basketball team to the City of Fountains during a press conference on Thursday ... noting the WNBA's recent success is appealing.

"It's kind of a no-brainer," Mahomes said.

Travis Kelce and Taylor Swift are "absolutely happy" in their highly publicized relationship ... with the Kansas City Chiefs superstar thanking his inner circle for protecting his "real" romance.

Trav expressed sincere gratitude to his "Grotesquerie" costar Niecy Nash-Betts during the most recent episode of his "New Heights" podcast with his brother, Jason ... praising the actress for remaining tight-lipped when folks hit her up for tea on his personal life.

NNB explained her phone's been ringing off the hook ever since the Ryan Murphy show aired ... with friends and interviewers trying to get some intel on not only what happens on the show -- but also all about Traylor.

Taylor Swift performed all weekend in Louisiana without her boyfriend, Travis Kelce, watching from the crowd ... but he was seemingly top of mind during her concert last night.

The pop star hit the stage for her sold-out Sunday show at Caesars Superdome in New Orleans -- and, while belting out her song, "Midnight Rain," she showed off a variation of Travis' signature pose whenever he makes a first down for the Kansas City Chiefs.

Check out the video ... Taylor uses her index fingers to simultaneously point to one side and then she blows a kiss to the crowd before twirling around and walking away.

Baby Mahomes number three is on the way ... but momma's still gotta get her workouts in!

Brittany Mahomes -- who this summer announced she was expecting her third child with Patrick Mahomes -- posted several shots on social media ... rockin' a cute bright orange two-piece exercise fit.

Britt, glowing, with an ever growing belly, looks great!

Marsha Kearney -- the mother of Kansas City Chiefs star Rashee Rice -- was slapped with a misdemeanor charge this month over allegations she stole her neighbor's package ... TMZ Sports has learned.

North Richland Hills Police in Texas tell us ... after Kearney's neighbor accused her of snatching some Chappell Roan records right off their porch in plain view of their Ring camera on Sept. 29, an arrest warrant for the 43-year-old was issued on Oct. 8.

Cops say Kearney ended up turning herself into the Tarrant County Sherriff's Office a week later -- on Oct. 15 -- and she was eventually charged with one count of mail theft.

Travis Kelce can't be at Taylor Swift's show tonight because of his NFL season,  but his family's showing love for his girlfriend .... hitting up the "Eras" tour in Miami.

Travis' brother, Jason Kelce, is at Taylor's Friday concert ... along with his wife, Kylie, and their daughter, Wyatt.

The family of three was spotted heading into Hard Rock Stadium ... and Travis' mother, Donna, was spotted inside the venue -- her very first "Eras" experience -- so there are at least 4 Kelces there.
