Taylor Swift lifts the lid on the early days of her relationship with Travis Kelce, saying they had a 'significant amount of time that no one knew' and were already a couple before she attended her first NFL game

Taylor Swift finally has opened up on her relationship with Kansas City Chiefs star Travis Kelce, revealing the power couple began their love story long before she made headlines by attending his games.

The pop star, 33, who was named TIME Magazine's 'Person of the Year', set the NFL ablaze when she became the headliner at the Chiefs' games to cheer on Kelce, 34. 

In the months 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.' 

Kelce, now infamously, first tried to capture Swift's attention when he attended her Eras Tour show at Arrowhead stadium in July, revealing on his New Heights podcast later in the summer that he made a friendship bracelet with his number on to give to the pop icon. 

He failed to meet Swift behind the scenes of her sold-out tour but his 'mental' podcast antics eventually caught her attention with the songstress revealing they began dating immediately. 

'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,' she 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.'
