Over the weekend, the NFL tight end and his superstar girlfriend, Taylor Swift, were spotted at the ultra-exclusive Bird Streets Club in West Hollywood where, a source told The Post, members such as Leonardo DiCaprio and Timothée Chalamet pay $10,000 a year.

The two seem to be playing it low-key while she takes a break from her world tour and he chills out after his Kansas City Chiefs won the Super Bowl. But Kelce’s wall could probably use a rest as well. One expert told The Post that his trip to see Swift in Singapore on March 8 could have cost nearly $570,000— and it’s just one of three far-flung private jet journey’s Kelce has taken, sometimes for just 14 hours, to catch up with her since their relationship went public last September.

“Travis Kelce always comes to play — not just on the field, but in his everyday romance with Taylor Swift — sparing no expense,” pop culture lifestyle expert Valerie Greenberg told The Post. “He isn’t afraid to open his heart and his wallet.”Indeed, with three Super Bowls under his belt, Kelce, 34, is in the third year of a four-year contract worth $57.25 million — making him the fourth-highest-paid tight end in the NFL, according to USA Today.

But he may be shelling out more than half of his annual $14+ million salary — as much as $8,232,229 million by The Post’s estimate — while dating a billionaire.Here’s a breakdown of the cost of winning Taylor Swift’s love.Insiders dished last year that, after hooking up with Swift, Kelce felt “self-conscious” about his, uh, humble seven-bedroom abode — purchased for $995,000 in 2019 — in Kansas City’s Briarcliff West neighborhood.

So he upgraded to a larger, flashier pad that also offers more privacy from paparazzi. In October, Kelce threw down $6 million for a 17,000-square-feet mansion, hidden behind a gate, in the Kansas City suburb “Leawood is one of the top 50 wealthiest towns in the US. It’s an upscale, private neighborhood … You have a lot of privacy and security compared to where he was before,” Corcoran real estate agent Amand

She added of the home, which is said to feature a sprawling pool, tennis court and mini golf course: “It’s a trophy property fit for a three-time Super Bowl Champion.”In November, Kelce flew private on a Friday to see Swift perform in Argentina — and flew back in time for a Monday practice, Page Six reported. That kind of trip costs around $300,000, Michael Giordano, partner and aviation specialist at Cirrus Aviation Services confirmed.

“There are a number of variable costs … but around $300,000 would be the approximate charge to charter a 10-seat private jet to fly from the US to an international destination round trip,” Richard Levy, a Dallas-based aviation expert and consultant who previously worked as a captain for a major US international airline, told The Post

Days after his Super Bowl win, Kelce reportedly flew from LA to Hawaii, then touched down in Sydney, Australia, on Feb. 21 to join Swift during a tour stop at Accor Stadium. Estimated cost: $340,000 for a 10-seat jet, Giordano confirmed.

On March 7, Kelce arrived in Singapore to catch Swift’s tour — flying out of his hometown of Cleveland, Ohio, with a group of pals. The 19-hour excursion, plus a refueling stop in Dubai, would likely cost around $570,000 for a 10-seat plane, according to estimates confirmed by Giordano. Though it’s possible that Swift gave him a seat on her own jet for some of the international legs.
