Watch Sia's latest video with Maddie Ziegler… for My Little Pony: The Movie

My Little Pony: The Movie type Movie

Sia's creative collaborations with teenage dancer Maddie Ziegler continues to expand — first with "Chandelier," then "The Greatest," and, now, with My Little Pony: The Movie. Yes, really.

We already knew Sia was participating the upcoming MLP flick as Pony pop star Songbird Serenade, so it would only make sense that she release a big song for the movie. The music video for "Rainbow," debuting exclusively above, is directed by Daniel Askill and features another impressive performance by 14-year-old Ziegler.

Cut between footage of Songbird Serenade performing for a packed crowd — which of course includes Twilight Sparkle, Rainbow Dash, and the rest of the Mane 6 — Ziegler dances on a stage of water, successfully battling and conquering the elements. As she smiles (yes, she's smiling in this one!) and twirls, don't miss the heart-shaped cutie marks on her cheek to match those on the animated Songbird Serenade.

My Little Pony: The Movie arrives in theaters on Oct. 6. The soundtrack will be released on Sept. 22 and is available for pre-order today.
