Travis Kelce's game-worn jersey sells for $37K after the tight end began dating Taylor Swift

Travis Kelce's stock has dramatically risen on and off the field in recent weeks and his old jersey has now fetched a handsome sum at auction. 

The Kansas City Chiefs star was already famous for his skill on the football field , having won two Super Bowls, but his notoriety has grown even more since he began dating Taylor Swift. 

And amid his high-profile love story with the pop sensation, the tight end is no longer just breaking records on the field but off it as well. 

The jersey that the 34-year-old wore during the Chiefs' 2019 win over the Los Angeles Chargers has just sold for $36,905 on Goldin Auctions. 

The sale marks a new record for a game-used item of Kelce's for the action and Goldin Auctions owner, Ken Goldin, told TMZ: 'He has always been popular but the success of the Chiefs, as well as the publicity he's gotten around his relationship with Taylor Swift, has added to his popularity and awareness among collectors.'

Kelce scored a touchdown in the jersey during the Chiefs' 24-17 win, which was part of the NFL's international series at the infamous Estadio Azteca in Mexico City. 

The NFLer and Swift have dominated headlines over the past few months after the songstress first attended one of Kelce's games at Arrowhead Stadium. 

The Anti-Hero hitmaker confirmed speculation that she was dating Kelce when she first cheered him on during the Chiefs' rout of the Chicago Bears in Week 3 of the season in Kansas City. 

Since kickstarting her romance with the two-time Super Bowl champion, Swift has attended five of her NFL beau's games, watching him lose for the first time in her presence on Sunday in frigid Green Bay. 

But the 12-time Grammy Award winner has revealed that they only brought their relationship into the footballing - and global - spotlight after a while of dating behind closed doors. 

'This all started when Travis very adorably put me on blast on his podcast, which I thought was metal as hell,' she told Time Magazine. 

'We started hanging out right after that. So we actually had a significant amount of time that no one knew, which I'm grateful for, because we got to get to know each other. By the time I went to that first game, we were a couple. I think some people think that they saw our first date at that game? We would never be psychotic enough to hard launch a first date.' 

She has since been spotted in the stands at Arrowhead another two times, as well as supporting him alongside her celebrity posse, including Blake Lively, Sophie Turner and Ryan Reynolds, at MetLife Stadium when Kansas City played the New York Jets and at Lambeau Field against the Packers on Sunday. 

The global icon has also become firm and fast friends with Chiefs quarterback and Kelce's pal Patrick Mahomes and his wife, Brittany, who has been spotted with Swift in private suites cheering on their men.

'When you say a relationship is public, that means I'm going to see him do what he loves, we're showing up for each other, other people are there and we don't care,' Swift, who was named Time's 'Person of the Year' on Wednesday, added.

'The opposite of that is you have to go to an extreme amount of effort to make sure no one knows that you're seeing someone. And we're just proud of each other.'

Despite dominating the spotlight at NFL stadiums across the country to the annoyance of many football fans, Swift insisted she doesn't mind 'p***ing off a few dads, Brads and Chads.'
