My Little Pony: The Movie: Sia joins cast

Sia is trotting toward Equestria for My Little Pony: The Movie.

The “Cheap Thrills” singer will play Songbird Serenade, a pony pop star that sports a mane akin to Sia’s signature headpiece: a black-and-white wig topped with an oversized bow.

The voice role marks Sia’s first official foray into acting, though she’s been dipping her toes into the film pool over the last few months. She performed Finding Dory‘s end-credit song, “Unforgettable,” penned Rihanna’s “Sledgehammer” for Star Trek Beyond, and lent her Diplo-assisted “Waving Goodbye” to the Neon Demon soundtrack. She’ll also contribute two original songs to My Little Pony.

The pop phenom boards an all-star cast, joining the previously announced Uzo Aduba (Orange is the New Black), Emily Blunt (Into the Woods), Kristen Chenoweth (Rio 2), Taye Diggs (Murder in the First), Michael Pena (Ant-Man) and Liev Schrieber (Spotlight). The actors who voice the TV series’ Mane 6 — Tara Strong, Cathy Weseluck, Andrea Libman, Tabitha St. Germain, and Ashleigh Ball — will also be reprising their roles for the big screen.

My Little Pony: The Movie follows the Mane 6 ponies as the venture outside Equestria to save their home. Friendship is Magic director Jayson Thiessen is helming the movie, and Meghan McCarthy, another Friendship is Magic veteran, wrote the screenplay with Rita Hsiao.

My Little Pony will hit theaters on Oct. 6, 2017. See a photo of Sia’s character below.
