Taylor Swift made a surprise appearance and performance at the Toy Story 5 red-carpet premiere in Hollywood on Tuesday, June 11 [1].

The appearance serves as a major promotional push for the film and its accompanying soundtrack, which features Swift's original song "I Knew It, I Knew You" [1, 2].

Swift arrived at the California event wearing an off-the-shoulder white Erdem mini dress styled to resemble the character Bo Peep [2]. While some reports indicate she wore a single white dress [2], other accounts state she wore two dresses throughout the evening [4].

During the premiere, Swift performed "I Knew It, I Knew You" for the gathered crowd [1]. The performance marks a high-profile collaboration between the artist and the film franchise ahead of the movie's wide release on June 19, 2026 [3].

The event combined high-fashion elements with the film's thematic imagery, as Swift's attire mirrored the aesthetic of the Toy Story universe [2]. This strategic alignment helps bridge the gap between the film's family-oriented audience and Swift's global fan base.

By integrating a global pop icon into the promotional cycle of a major animation franchise, Disney and Pixar are leveraging Swift's massive cultural reach to maximize opening-weekend visibility. The use of a character-themed costume further blends the brand identity of the film with the personal brand of the artist, creating a viral marketing moment that appeals to multiple demographics simultaneously.
