The Cruel Summer hitmaker, 33 - who was spotted with her A-list entourage at the anticipated game against the New York Jets - was seen excitedly supporting the NFL star, also 33, with her pals close by.
She put on a stylish display as she arrived to the stadium located in East Rutherford and donned a long-sleeved, plain black shirt that was tucked into the waist of high-waisted shorts.
The $695 shorts- from the brand called Area - contained sparkling, rhinestone embellishments on the front and the right pocket for a unique flare.
Throughout the night, Swift also threw on a black, leather jacket to help her stay warm in the cooler, fall temperatures.

The Grammy winner's blonde locks were parted in the middle and effortlessly flowed down past her shoulders, allowing her bangs to gently fall onto her forehead.
Taylor opted for minimal accessories to allow her outfit to be the main focal point for the big game, and added a flashy, gold-chained necklace as well as a dainty bracelet on her right wrist.
The performer's makeup was classically done for the night, and Swift was seen wearing her signature red lipstick.
She completed her overall ensemble by slipping into a pair of black, knee-high boots to coincide with the color scheme of her fashionable outfit.
Shortly before the nail-biting game kicked off, the songstress was seen arriving to the stadium with a group of her A-list pals in tow. Longtime friend, Blake Lively as well as her husband, Ryan Reynold, were seen tagging along.
Her new BFF, Sophie Turner - who recently split from Joe Jonas - was also seen standing next to Swift inside a VIP box to watch the Chiefs battle the Jets.
Sabrina Carpenter - who is slated to open for Taylor in upcoming international Eras Tour dates - was also seen joining in on the fun, while Hugh Jackman was also spotted amongst the star-studded entourage following his shock split from Deborra-Lee Furness.
Others that stopped by the game to cheer on the Chiefs included Swift's brother Austin Swift, Queer Eye star Antoni Porowski, filmmaker Shawn Levy, Blake Lively's sister and actress, Robyn Lively, and Taylor's backup dancer, Melanie Nyema.

The performer was previously seen supporting Kelce at the Chiefs vs. Bears game last weekend - which resulted in a win for the Kansas City-based team.
She sent not just Swifties into a frenzy, but also NFL fans when the hitmaker stood closely next to Travis' mother, Donna, in a VIP suite at Arrowhead Stadium.
After the game, the singer and sports star were spotted leaving the Chiefs locker room together, and enjoyed a private dinner date at Prime Social Rooftop located in Kansas City.
The NFL pro reportedly 'bought out the restaurant for his family and team,' per Entertainment Tonight, and the group stayed out until 2am. Both Taylor and Travis were also spotted driving in his vintage convertible in the city.
While at the eatery, Taylor was seen affectionately wrapping her arm around Kelce as they had the chance to spend time together in photos obtained by TMZ.

He could be seen keeping it casual as she sported a black T-shirt as well as a black cap placed on top his head as he entered a small side entrance.
Back in July, the Chiefs star first expressed his interest for Swift on his podcast that he hosts with brother, Jason, called New Heights With Jason and Travis Kelce.
The sports star revealed that he had attended Taylor's Eras Tour concert stop in Kansas City and had wanted to give the singer his phone number - but the plan didn't exactly pan out.
On The Pat McAfee Show last week, he revealed he had extended an invitation for Swift to attend a game at Arrowhead Stadium, stating, 'I threw the ball in her court.'
The singer did indeed show up, and was also seen sharing special moments with his mother, Donna, who was also in the VIP suite.
During the latest podcast episode hosted by Travis and Jason that dropped earlier this week on Wednesday, the Chiefs tight end briefly touched on the frenzy now surrounding both him and Taylor after she showed up at his game.
'We've been avoiding this subject out of respect for your personal life. But now we gotta talk about it,' Jason told his brother.

Sweet shout out: 'Shout out to Taylor for pulling up,' the sports star stated. 'That was pretty ballsy,' and then he sweetly added that the singer 'looked amazing' last week on Sunday
Travis replied, 'My personal life that's not so personal. I did this to myself Jason. I know this,' and added that he was on the 'roller coaster of life.'
'Shout out to Taylor for pulling up,' the sports star then stated. 'That was pretty ballsy.' He then sweetly added that the singer 'looked amazing.'
'I just thought it was awesome how everyone in the suite had nothing but great things to say about her. The friends and family. She looked amazing, everybody was talking about her in a great light.'
'On top of that, the day went perfect for Chiefs fans of course. We script it all ladies and gentlemen. It was just impressive,' he explained, and admitted, 'It's definitely a game I'll remember.'
