The Swifties are sleuthing.

After Taylor Swift told MTV Video Music Award viewers Wednesday that Travis Kelce was present on the set of her “Fortnight” music video, fans searched for clips in behind-the-scenes footage.

Social media users highlighted one video of the pop star, 34, throwing a cart at an opening in a wall — only for it to bounce back in her direction.

In the midst of Swift’s and one of her crew members’s startled reactions, a loud laugh could be heard from off camera.

“IS THAT TRAVIS’ LAUGH???” one fan asked via X. “HOW DID WE NOT CATCH IT.”

Another added, “someone pointed out that the laugh when the glass doesn’t break sounds like travis…. like i don’t want to be that delusional but it does kinda sound like him?”

Swifties wrote that they have heard his laugh “enough times” on the “New Heights” podcast.newheights/Instagram

Many agreed, with one noting that they had listened to Travis, 34, and his brother, Jason Kelce, laughing “enough times” on their “New Heights” podcast to know the sound.

“I thought it was him from the first time we got the behind the scenes video. I just thought I was too delusional,” one Swiftie wrote, with another pointing out that they “said that in April and got s–t for it.”

Swift gushed about her partner’s presence on set while she and Post Malone accepted the VMA for video of the year.

“I would always just hear someone cheering from across the studio where we were shooting,” the “Bad Blood” singer recalled in her speech. “And that one person was my boyfriend, Travis.

“Everything this man touches turns into happiness and fun and magic, and I want to thank him for adding that to our shoot because I’ll always remember that.”

The Kansas City Chiefs player did not attend the awards show at UBS Arena in New York due to work commitments, so Swift walked the red carpet solo.

The Grammy winner stunned in a plaid bustier and skirt, completing her look with black hot pants and leather gloves.

The appearance came on the heels of her and Kelce’s jam-packed weekend in New York City.

The duo were photographed out to eat multiple times, also attending a wedding and the US Open men’s final.
