In the clip, which was captured by an onlooker who was sat just below the VIP Suite at the game, the pair could be seen exchanging ideas and practicing, without knowing that the handshake would soon become one of the most talked about moments of the night.

When Taylor Swift and Brittany Mahomes showed off the special celebratory handshake they had created at the Kansas City Chiefs’ game on Sunday, it sparked a fierce reaction online

Now footage has emerged that shows how the two stars put together the viral move right there in the audience of the sporting event

Taylor appeared to suggest that the handshake include a fist pump, while they also tried out a spin.

The Cruel Summer songstress then proposed a little dance move that involved her moving her arms in a circular motion as she shook her body and stuck out her tongue.

In the end, however, the routine featured them slapping hands, grabbing one another by the arm, and bumping hips.

It’s unclear who originally shared the video, but it was reposted to TikTok as part of montage of clips taken throughout the sporting event by a woman named Katelyn Martini, where it gained more than 1.6 million views.

The ladies’ handshake had a mixed reaction from social media users – some people were unamused with it and branded it as ‘cringe,’ while others loved it and described the new pairing as ‘friendship goals.’

Afterwards, body language expert Judi James analyzed Taylor and Brittany’s interactions from the game exclusively for DailyMail.com, and she said they looked ‘rehearsed,’ which left her wondering it was all an ‘act’ and a part of the hitmaker’s ‘masterplan’ to ‘submerge herself’ into her new boyfriend’s world.

‘Taylor’s masterplan for total immersion into the role of Kelce superfan involves some teenager-with-a-crush rituals that are getting more pronounced on a daily basis,’ Judi said.

‘Has anyone ever tried this hard to submerge themselves into their boyfriend’s culture and team identity? Especially an A-list artist.

‘Taylor’s cosplay looks complete here as she shows off the results of what looks like some induction training from real WAG Brittany.

The singer, 33, and the former soccer star, 28, were seen doing the routine as they cheered on their respective partners: Travis Kelce , 34, and Patrick Mahomes, 28

‘Suddenly, she and Brittany are acting like besties, grabbing at each other as the action on the pitch gets tense.

‘And then there’s the perfectly-choreographed celebratory special handshake that gives the impression that Taylor is now totally part of the Chiefs family.’

Judi explained that Taylor looked like she was trying to ‘copy’ Brittany throughout the game, pointing out that she ‘followed suit’ in everything that the 28-year-old did, while comparing her to a dancer who ‘hasn’t quite learned the choreography yet.’

‘Brittany initiates the nail-biting and celebratory movements and rituals as the game progresses – and Taylor is left to follow suit,’ she continued.

‘Taylor looks as though she has been dropped on the set of a new video that she hasn’t quite learned the choreography for yet.

‘Her body language is out of sync with Brittany’s, apart from the rehearsed-looking special handshake.

‘When Brittany does a little dance it’s Taylor who is left copying that dance, as though trying to memorize the steps.’

Ever since she started dating Travis last month, Taylor has buddied up with Brittany, who married Patrick in March 2022 and shares two kids with the football star

Earlier this month, they were seen grabbing dinner alongside many of Taylor’s A-list friends – like Blake Lively and Sophie Turner – and they’ve sat in the same suite at a other Chiefs games

Judi said their behavior made it seem like they were trying to ‘act as though they’ve been friends for years’ – but she could see through the façade.

‘Brittany’s body language hints that she is keen to show she’s not going to lower her own status just because she’s with a global star,’ she added.

‘There is a display look to these two women’s signals that suggests the friendship might not be quite as deep or mature as Taylor is trying to portray.

‘It is a sign that she is trying very, very hard to ingratiate herself with the people that matter to Travis.’
