Could a Taylor Swift collaboration be the next big reveal for Toy Story 5? Fans are currently buzzing with excitement after a cryptic promotional billboard for the upcoming film surfaced, hinting at a potential connection to the pop superstar.

The mystery began on Friday, May 29, when a billboard emblazoned with the initials “TS” appeared against the franchise’s signature sky-blue, cloud-dotted background. Naturally, the internet’s most attentive detectives—the Swifties—immediately took notice. By counting 13 clouds on the display, fans were quick to link the imagery to Swift’s well-known lucky number.

“13 clouds and ‘TS’? There’s no way this is a coincidence,” one fan remarked on X. “The theories are officially spiraling.”

The speculation reached a fever pitch on Saturday, May 30, when Pixar shared the image on social media. The post featured the beloved character Jessie posing atop the billboard with the caption, “She’s making those moves up as she goes!” Devoted fans immediately recognized the line as a clever nod to the lyrics from Swift’s 2014 chart-topping anthem, “Shake It Off.”

Swift famously sings, “I’m dancin’ on my own / I make the moves up as I go,” a callback that has the fanbase convinced a musical crossover is in the works. From hopeful calls for a new soundtrack contribution to joyous reactions from millennial fans, the social media discourse suggests this campaign is already a hit.

Billboard has reached out to representatives for Swift regarding the rumors.

This potential celebrity involvement follows Pixar’s recent announcement that Bad Bunny has officially joined the Toy Story 5 voice cast, portraying a character known as “Pizza with Sunglasses.”

As the film prepares for its June 19 release, it promises to bring back franchise icons including Tom Hanks as Woody, Tim Allen as Buzz Lightyear, and Joan Cusack as Jessie. The story will center on the gang as they navigate the challenges of modern technology, squaring off against a high-tech rival named Lilypad.
