Taylor Swift and Brittany Mahomes have further solidified their BFF status as the pop singer borrowed a red teddy coat from Patrick Mahomes’ wife while cheering on Travis Kelce in Green Bay on Sunday.

The Bad Blood hitmaker, 33, was spotted stepping onto a private jet with Brittany, 28, as they flew to Wisconsin to watch the Kansas City Chiefs take on the Green Bay Packers at Lambeau Field.

The Grammy winner was seen donning an all-black ensemble that was layered with the thick, red coat as she proudly supported her boyfriend, 34, at the anticipated game – which resulted in the Packers winning 27-19.

Swift and Mahomes have been spending time together since the star’s romance with the Chiefs tight end came to light.

Earlier this week on Friday, both Taylor and Travis joined Brittany as well as her husband Patrick for a festive Christmas bash in Missouri.

Taylor was spotted flashing a big smile as she made a grand arrival to Lambeau Field, with Brittany close by her side.

Along with sporting a long-sleeved, black shirt and a stylish miniskirt, the songstress added a red coat on top – which her new BFF has been seen wearing on various occasions in the past.

Her blonde locks were swept back into a chic up do, allowing her bangs to fall down straight onto her forehead.

She added a silver necklace on top of the shirt to add a flashy flare to her overall look for the big night.

Brittany was also decked out in Chiefs colors, and wore a red shirt as well as a pair of black pants and over-the-knee, black boots.

The mother-of-two added a varsity jacket to complete her outfit that had her husband’s number 15 on the upper left side.

Earlier on Sunday, both Swift and her close pal were spotted stepping onto a jet at Charles B. Wheeler Downtown Airport in Kansas City in photos obtained by DailyMail.com.

Brittany was seen arriving to the plane first as she climbed out of a sleek, Lamborghini SUV ahead of the game.

Only a few minutes later, the Love Story hitmaker was also seen arriving in a black GMC to board the jet.

Kelce notably flew to Wisconsin one day earlier on Saturday to join his Kansas City Chiefs teammates before playing against the Packers.

And on Thursday, Swift made a glamorous appearance while attending the star-studded premiere of Beyonce’s movie called Renaissance: A Film By Beyonce.

She showed off her stunning frame wearing a glittering, silver dress that contained straps that wrapped around her shoulders.

Not long after the screening – where she also crossed paths with BFF Blake Lively – Taylor quickly flew back to Kansas City to spend time with her new beau, Kelce.

Earlier this week on Tuesday, a moving truck was seen outside of the NFL player’s $6 million mansion as the singer moved into the sprawling home.

A source recently told DailyMail.com, ‘While Taylor is not officially moving in with Travis, her friends and family believe she isn’t exactly moving out either.’

‘Everyone truly believes that Taylor and Travis are soulmates. Taylor also believes this, as does Travis.’

‘They are both absolutely obsessed with each other and yes, very much in love. They want the same things in life – a future and possibly a family.’

‘If things continue going the way they are going they will continue to cohabitate because that is what couples in love do. This is kind of like a practice run in a sense,’ the insider continued.

The pair’s budding romance first came to light when Taylor was seen attending the Chiefs game as the team competed against the Chicago Bears in late September.

She has supported Kelce by cheering him on at other games, and the two have also enjoyed date nights in New York City.

On Friday, Travis and Taylor joined Brittany and Patrick Mahomes at a Christmas party at what seemed to be the Miracle On Main Street event in the heart of Kansas City.

The Mahomes’ embraced the holiday season by wearing matching, reindeer onesies and the new power couple were also spotted joining in on the fun.

As their romance continues to stay in the spotlight, Kelce recently gave his girlfriend, Swift, an adorable nickname just three months after they were first romantically linked.

The Kansas City Chiefs tight end referenced to the Grammy winner as ‘Tay’ on the latest episode of his New Heights podcast with brother and Philadelphia Eagles center, Jason Kelce.

The moniker was revealed when the two NFL stars discussed an Instagram post that celebrated Travis becoming the fastest tight end to reach 11,000 yards after competing against the Las Vegas Raiders on Sunday.

The singer liked the post, and her beau sent a shout out to the songstress, stating, ‘Thanks Tay. Appreciate you on the Chiefs page supporting. What’s the next question?’

Jason continued the conversation by asking, ‘Has she always been a fan of tight ends receiving yards?’

‘I’m not sure. That’s a good question. Maybe, I don’t know if she’s a fan of tight ends or not,’ Travis quipped in response.

His brother had initially sparked up the topic, telling the Chiefs star, ‘You may not care about records but do you know who does? A 92 percenter by the name of…Taylor Swift.’

92 percenters are notably the nicknames given to fans and listeners of the New Heights podcast.

‘That’s right, she liked an Instagram announcement from the Chiefs about you breaking this record,’ Jason continued.

Earlier last week, the pro football player opened up about his whirlwind romance with Swift during an interview with the Wall Street Journal.

‘I’ve never been a man of words,’ he expressed to the outlet, and gushed, ‘Being around her, seeing how smart Taylor is, has been f***ing mind-blowing. I’m learning every day.’
