Her blonde locks flowed down past her shoulders, and were partially covered by a white and red-striped beanie that had Kelce’s jersey number, 87, printed in black at the front.

The pop star slipped into a pair of sheer tights as well as black shoes to complete her overall look for the big day.

Swift added chunky rings on each of her hands to accessorize the outfit and also wore her classic, red lipstick as a final touch.

Sunday’s game was the seventh in total that Taylor has attended to cheer on her beau – whom she began dating over the summer.

The Grammy winner was also accompanied by her father, Scott, who sported a red and black-colored Chiefs sweater, despite being a Philadelphia Eagles fan.

Her father previously met Kelce during the singer’s concert stop in Argentina last month which the pair both attended, and Scott notably was seen wearing a Chiefs lanyard at the time.

Brittany Mahomes – the wife of Chiefs quarterback Patrick Mahomes – was also seen near the Love Story singer for portions of the game.

Taylor’s new BFF donned a black ensemble which was layered with a fashionable, white coat that she chose to leave unbuttoned.

At one point, Swift was seen excitedly lifting the mother-of-two into the air as they celebrated the Chiefs scoring a touchdown.

She could be seen intently viewing the game from a VIP box at the venue, and donned a gray Chiefs sweatshirt as well as a plaid miniskirt

Alana Haim, who is known for being a member of the rock Haim, showed off her Chiefs pride in a Kansas City jacket and light, denim jeans.

She was spotted applauding and cheering on the team as she sat amongst the A-list crowd in the VIP box suite at Gillette Stadium.

The Chiefs had a rough start to the game and initially trailed behind the Patriots – until the Kansas City based team took the lead at the end of the first half.

At one point, Taylor was spotted yelling out ‘f**k’ in frustration as she watched Travis drop the football in the end zone during a play.

Not long after the game ended, Kelce was seen leaving the stadium with his other teammates on a bus in exclusive photos from DailyMail.com. However, his girlfriend was nowhere in sight.

The NFL player dressed warmly in a dark green, turtleneck sweater and tan-colored trousers while strolling outdoors.

He also carried a large duffle bag in his right hand as well as bottles of Gatorade to help him stay hydrated.

The pop songstress later shared Instagram snaps capturing her epic celebrations, which saw Swift party the night away inside an eatery alongside her pals and various ‘squad’ members.

The snaps depicted the singer posing up with friends Blake Lively, Gigi Hadid, Sabrina Carpenter and more – but no sign of her boyfriend Travis Kelce.

She was presented a frosted, layered cake by Zoe Kravitz, and enjoyed a yummy cocktail alongside Jack Antonoff.

She displayed her cheeky side as she stuck out her tongue for the camera and clutched her nearly empty beverage.

‘Can’t believe this year… actually… happened? Thank you for all your beautiful birthday wishes yesterday,’ she captioned the post.
