Jason and Donna Kelce arrive in Kansas City to celebrate Travis’ birthday

Taylor Swift fans are eager to see whether the pop icon will touchdown in Kansas City today to celebrate boyfriend Travis Kelce’s birthday.

But the Chiefs tight end will at least turn 35 with his brother Jason and his parents Ed and Donna, who were seen shortly after touching down in Kansas City alongside Jason’s wife Kylie.

The siblings will kick things off Saturday afternoon by hosting the second annual Kelce Car Jam, a showcase of muscle cars and swish rides belonging to Kelce and his motoring enthusiast buddies. Fans will be hoping to catch a glimpse of the three-time Super Bowl winner’s 1970 Chevy Chevelle – the timeless classic he drove away from a game last October with Swift, 35, in the passenger seat.

Proceeds from the charity block party are going to Kelce’s 87 & Running Foundation which raises funds for needy kids in Kansas City and Cleveland.

Speculation about Taylor heading to Kansas City has swirled all week with a rumor circling about her hiring out a popular barbecue joint Wednesday night for a pre-birthday celebration.

There have been no confirmed sightings of the Bad Blood singer, however, who has made considerable efforts to mask her flight details and whereabouts since the foiled terror attack at her Vienna concert in August. Swift wasn’t there to watch the Chiefs beat the Los Angeles Chargers 17-10 last Sunday.

But, according to one well-placed source, her absence is no indication that her romance with Kelce is cooling off. Swift simply doesn’t see much of her boyfriend when he’s playing away games.

And this season is expected to mostly stick to attending the Chiefs’ home games at Arrowhead Stadium, potentially including Monday night’s clash with the Saints.

That arrangement means they can instead enjoy quality quiet time at the sprawling $6million home Kelce bought last year in an exclusive Kansas City suburb. Set in the manicured grounds of a gated community and far from the public gaze it is the perfect bolt-hole for the A-list couple to stage low-key dates, dinners and movie nights.

Kelce and Swift did venture out undetected late last month when swish Kansas City eatery Noka was reportedly closed to the public so they could enjoy an intimate catch-up.

According to Deux Moi, ‘The restaurant was claiming it was closed for maintenance but it’s the same restaurant where Brittany Mahomes had her birthday dinner not very long ago.’

That came on the heels of a bumpy period for Kelce and Swift, who recently celebrated one year of having made their romance official with the anniversary of the singer’s first public attendance of a game at Arrowhead Stadium on September 24.

Only a couple of weeks earlier they were forced to defend themselves against allegations that the whole relationship was a PR sham following an alleged leak of documents purporting to be from Kelce’s public relations.
