CBS’ star analyst Tony Romo appears to have accelerated Taylor Swift and Travis Kelce‘s relationship, after inadvertently calling the pop superstar a ‘wife’ live on TV.

Swift was once again in attendance at Arrowhead on Sunday afternoon to watch her boyfriend in action, after hot-footing it from New York in her private jet just a few hours earlier.

And while there are rumors flying around that Kelce is planning to propose in the coming days, Romo seems to know more than the rest of us, accidentally calling Swift ‘Kelce’s wife’ on commentary.

Broadcasting live to millions across the world, Romo can be heard talking over a play involving Kelce when he said: ‘Kelce’s wife, Taylor Swift, in the audience.’

Fans immediately took to social media to react to the bizarre moment, with one Swiftie noting: ‘Does he have insider information?’

In the game itself, the Buffalo Bills raced into a 14-0 first-half lead, much to the disappointment of Swift and the Kelce family watching on from the suites at Arrowhead.

Before halftime though, the Chiefs did get a score, leading to a wild reaction from Swift – who banged on the glass in the suite and repeatedly said ‘YES, YES’ when caught by TV cameras.

Earlier in the day, DailyMail.com’slusive photos showed Swift touching down in Kansas City, after her private jet left New Jersey three hours earlier.

She was then spotted arriving at the game in a red Chiefs jumper, once again repping her boyfriend (or should that be husband?) at the game.

Earlier in the week, reports claimed that Kelce is planning a surprise party for Swift’s birthday next week and there are suggestions the NFL star could even propose.

Swift turns 34 on Wednesday, December 13 and her whirlwind romance with the Kansas City Chiefs star has taken the world by storm since they went public back in September.

DailyMail.com exclusively reported that pop star Swift was moving in to Kelce’s stunning $6million mansion in Kansas City after returning from her South America Eras tour in November, a signal of how well things have gone between the pair.

And now, a bombshell report in Life and Style claims the Chiefs star is pulling out all of the stops for her birthday next week.

The publication quotes an insider as saying: ‘They already know they’re compatible, but living together for an extended period will be the ultimate test.

And as for her birthday celebrations, the insider was quoted as saying: ‘Travis has something special planned.

‘He’s arranged a very intimate romantic dinner just for the two of them, and is also trying to pull off a semi-surprise party with the help of some of her closest friends.

‘There are whispers that he could use the opportunity to propose — that’s what everyone, including Taylor, is hoping for!’
