Steamy picture of Taylor Swift and Travis Kelce emerges as his reaction to shock Nashville performance is revealed

Taylor Swift and Travis Kelce packed on the PDA as they reached a major milestone in their high-profile romance. 

The couple sent fans wild earlier this week when they made their first joint appearance at an event during the NFL star's Tight End University in Nashville. 

While Kelce was technically working at the three-day NFL event, which he has co-hosted alongside fellow tight ends George Kittle and Greg Olsen since 2021, he couldn't keep his eyes - or his hands - off his pop sensation girlfriend. 

Photos have begun to trickle out from the 'Fortnight' hitmaker's shock appearance at the event in Music City with one particularly steamy moment between an unsuspecting Kelce and Swift being caught on camera. 

In a snap that has emerged from Monday night's launch party at cocktail bar LA Jackson, the loved-up couple could be seen sharing an intimate moment in the background. 

The 14-time Grammy Award winner had her arms wrapped around the NFL star's neck as she leaned in to the beaming Kelce. 

One night on from the racy moment, the songstress proved she can still keep her NFL beau on his toes when she shocked him with a surprise performance. 

Kelce and Swift had earlier been pictured arriving at the Brooklyn Bowl in Nashville, where it seemed like Swift was purely just supporting Kelce for a cause close to his heart.

Singers such as Sophia Scott, Graham Barham and Chase Rice were all listed to perform at the venue, where Swift was first spotted enjoying the night in the VIP section. Jordan Davis also played and welcomed country star Luke Combs onto the stage but Swift's involvement had been kept a secret - if it was even scheduled at all.

Swift told the crowd 'we planned that three minutes ago' shortly before she left the stage to huge cheers. Just when it seemed like Brown was finishing his set, Swift ignited a frenzy when she walked out for one more song and played an acoustic guitar belonging to Rice. 

She dedicated it 'to our favorite players' before launching into a rendition of one of her biggest hits and sending the crowd - and Kelce - wild.

The three-time Super Bowl champion was spotted watching his girlfriend's impromptu performance from backstage, excitingly exclaiming, 'Let's go,' as she wowed her riveted audience. 

It was an intimate venue for Swift to perform in after selling out the biggest stadiums around the globe on her historic Eras Tour.

Nashville's Brooklyn Bowl hosts up to 1,200 people while her biggest Eras show was at the Melbourne Cricket Ground in Australia, where 96,000 people went to see her.

San Francisco 49ers star Kittle and Olsen, now a distinguished NFL analyst following his career in the league, run the event alongside Kelce. 

And the trio of tight ends and their respective partners spent the night mingling and enjoying themselves. The 'Anti-Hero' singer even took a bathroom mirror selfie with Claire Kittle and Sierra Pearson, who is dating Claire's brother, former Iowa basketball player Riley Till. 

As well as building a community among the players who play in the position that Kelce is famous for and sharing tips on performance, they also raise money for charity through the annual get-together.

Earlier in the day, Kelce had stunned NFL fans when video emerged of him being a coach for one of the football classes scheduled for the day.

The 35-year-old explained his running style during certain routes in passages of play and the clip caused a stir on social media from fans and analysts alike.  

'Us big guys, it's so hard for us to throw one foot in the ground going at 75% speed in a route to get out there,' the 6ft 5 Kelce was filmed explaining.

'We want to use two steps, and sometimes it takes three on the 15, 20-yard routes if you are lucky enough to run them. But for me, getting in and out of a break, you have to slow that momentum down and really gather that power before you can explode out.'

James Palmer, an NFL reporter for Bleacher Report, commented on the video on Instagram saying: This is so damn good. I've talked to a number of safeties over the years that have all said, Kelce is never moving that fast or even running 100% all that often.

'He'll never run by you, but staying with him is impossible because every step has a purpose and the change of pace with each step or break keeps you so off balance in coverage. This is a master class right here.'

Kelce, 35, nearly retired when his Chiefs team lost the Super Bowl in February but chose to play on because he didn't want his career to end on such a low note.

He would almost certainly still be involved in this week's event even if he had called it a day but now, Kelce is gearing up for the 2025 campaign.

The Chiefs begin the new season on September 5 in Brazil against the Los Angeles Chargers.
