Taylor Swift has released a new song for the Toy Story franchise, titled “I Knew It I Knew You,” co-written with frequent collaborator Jack Antonoff. The track, inspired by the character Jessie, arrives with a childhood video of Swift dressed as the cowgirl. According to the source report, Swift thanked co-writer Andrew Stanton for imagining her for the role and acknowledged Randy Newman’s contribution to the film’s soundtrack. The announcement teases a “rootin’ tootin’” musical departure but leaves key questions unanswered about the project’s format.

How Jessie Became Swift’s Childhood Alter Ego

The singer’s video — an adorable throwback of herself in full cowgirl Jessie costume — underscores a personal connection that predates the song. Swift has long cited Toy Story characters as influences , saying they made her laugh and taught her lessons throughout her childhood, the source reports. By channeling Jessie, the exuberant cowgirl from the franhise’s second film, Swift taps into a nostalgia that resonates with millennial fans who grew up alongside the Pixar series. This isn’t merely a celebrity cameo; it’s a deeply felt homage to a character who, like Swift’s own public persona, embodies resilience and spunky independence.

A Songwriting Reunion with Jack Antonoff in Pixar’s Orbit

“I Knew It I Knew You” marks another collaboration between Swift and producer Jack Antonoff, whom she calls a “pal.” The duo has co-written many of her recent albums, including Folklore and Midnights, but this Pixar project represents a stylistic shift. Swift described writing the track as a “musical departure and coming home at the same time,” according to the source. The involvement of Antonoff suggests the song may blend Swift’s signature pop-folk sensibilities with a cinematic, Western-inflected sound befitting the Toy Story universe.

Randy Newman’s Legacy and Swift’s ‘Rootin’ Tootin’’ Departure

Swift specifically thanked Randy Newman, the legendary composer behind the Toy Story scores and songs like “You’ve Got a Friend in Me.” Her acknowledgment signals respect for the franchise’s musical heritage. Calling the new track a “musical departure,” Swift hints at a genre exercise that stretches her range — perhaps incorporating folk, country, or bluegrass elements — while still feeling instinctive . Whether the song will appear in a full-length feature or a standalone short remains unconfirmed by the source.

What We Still Don’t Know About the Toy Story Project

The source report does not specify which “latest addition” will feature the song. Pixar has annuonced Toy Story 5 for a 2026 release, but Swift’s involvement in that film has not been confirmed. The song could instead be part of a short film, a special, or an album tie-in — or a standalone single for a franchise event. Additionally, no release date for the song is given; the announcement appears to be a teaser. The absence of details from either Swift’s camp or Pixar leaves fans guessing whether this is a one-off or the beginning of a deeper collaboration.

Broader Context: Swift’s Soundtrack Evolution

This is not Swift’s first foray into soundtrack work. She previously contributed “Only the Young” for the documentary Miss Americana, “Beautiful Ghosts” for the Cats film, and two original songs for The Hunger Games series.. A Pixar partnership, however, would be her highest-profile family-friendly venture, aligning with her recent re-recording project and growing catalog for all ages. as the source notes, Swift’s childhood adoration for Toy Story makes this a “dream come true” — a statement that positions the collaboration as emotionally authentic rather than transactional.
