spent roughly 48 hours in Australia last week, visiting his girlfriend, international singing star Taylor Swift.

Nearly that entire two-day visit was under the microscope.

Cameras were trained on the private jet that landed in Sydney, and photos and videos emerged from the trip Kelce and Swift took to the zoo. Even more attention was paid to Kelce when he attended one of Swift’s concerts and was given friendship bracelets by Swifties, while he handed out guitar picks.

The intense scrutiny given to Kelce and Swift is the focus of a new documentary that has two colons in the title. “TMZ Investigates: Taylor & Travis: Ultimate Love Story” will air Monday at 8 p.m. on Fox 4.

TMZ said Phil McGraw (better known as Dr. Phil) will share how “the biggest threat to the pop idol and the NFL star is their jam-packed schedules … not allowing them to spend enough quality time together.”

The documentary also features Dallas Mavericks minority owner/”Shark Tank” star Mark Cuban and Patti Stanger, who was on “The Millionaire Matchmaker” show, TMZ said.

Here is a preview of the hour-long documentary, which will air nearly five months after Swift attended her first Chiefs game.

Parade magazine said the TMZ documentary will be available for streamers Tuesday on Hulu.

This is the second news special about Kelce and Swift. In December, Hulu had a magazine special called “Taylor + Travis: A match made in music, sports heaven.” It was a “Nightline” and ABC News collaboration.
