Taylor Swift picks yellow daisy-embellished dress for surprise ‘Toy Story 5’ performance

Taylor Swift brought the sunshine at the “Toy Story” 5 premiere.

The singer surprised fans on Tuesday night when she changed into a second look after the red carpet, performing at the Dolby Theater alongside Randy Newman.

Swift, 36, swapped her Erdem mini for a yellow Oscar de la Renta gown ($8,990) that was embellished on top with all-over flowers appliqués.

Her hair was pulled back in a low braid, though she kept her signature red lip glam for the on-stage performance.

Swift’s jewelry matched the colorful blooms of her dress, wearing an amethyst and citrine pendant necklace and matching drop earrings.

Marking the live debut of her new original song for the animated film’s soundtrack, “I Knew It, I Knew You,” she also performed a duet with Newman, singing “You’ve Got A Friend in Me” as the Newman accompanied her on the piano.

“Writing this song felt like a musical departure and coming home at the same time,” Swift wrote on Instagram, adding, “Creating something for Jessie was a new challenge and also felt like second nature all at once.”

Her floral performance look was perfectly on-theme as the original piece opens with the lyrics: “I knew you through the daze of the blades of the grass in summer.”

Earlier in the evening, Swift walked the red carpet wearing a patchwork minidress by Erdem that boasted a corseted top and sculptural skirt.

She pulled her hair back into a half-up style with a braid, adding a diamond horseshoe pendant necklace as a nod to cowgirl Jessie.

Adorably, in lieu of a bag on the red carpet, she carried her personal 1995 VHS tape of “Toy Story,” which she asked both Tom Hanks as well as Tim Allen to sign.
