And her legion of fans will add to an already massive audience tuning in to see the Chiefs take on the San Francisco 49ers in Las Vegas.

Swift was expected to land here in the Nevada desert last night after a frantic dash from her latest tour date in Tokyo.

She and Kelce, both 34, have been tight-lipped on whether she would make it to Vegas.

But the Japanese embassy remarkably released a statement reassuring fans she would have plenty of time.

Bookies have even offered odds on Kelce to propose at Allegiant Stadium.

The biggest America TV audience for a Super Bowl to date was the 114.8 million nine years ago.

But that is expected to be obliterated tonight given Swift has brought new audiences to the NFL.

A 30-second slot to advertise during the game on host broadcasters CBS costs £5.5m.

Chiefs merchandise sales went through the roof the day after Swift was spotted cheering on Kelce in September.

And Kelce has earned more than a million new followers on Instagram since the love story began.

The pair put on a loved-  up display on the field after the Chiefs booked their Super Bowl spot with a win over the Baltimore Ravens a fortnight ago.

Swift then cleaned up at last weekend’s Grammys before jetting off to Tokyo.

Kelce has said: “She’s unbelievable. She’s rewriting the history books  herself. I told her I’ll have to hold up my end of the bargain and come home with some hardware, too.

“She has definitely brought a lot of new faces to the game.”

Swift’s  screen time has led to complaints from some traditional NFL fans that she is ruining their enjoyment of the game.

Donald Trump backers have even speculated that the relationship is part of a plan to ‘rig’ the Super Bowl for the Chiefs and help get Joe Biden re-elected as President in November.

Swift has previously endorsed the Democrats.

But NFL commissioner Roger Goodell said: “The idea that this is within a script, this is pre-planned, is just nonsense.

“The Taylor Swift effect is all positive.

“It creates a buzz so another group of young fans, particularly young women, are interested in seeing why she is interested in this game.”
