Sia has recruited German supermodel Heidi Klum and Game Of Thrones' Pedro Pascal to star in her new Fire Meets Gasoline music video.
Sexy Klum, who wears nothing but items from her signature lingerie collection for the promo, admits she was delighted to be a part of a Sia project.
She says, "Sia is one of those incredible artists who puts so much passion into her work, and I am thrilled to be part of a music video.
"I remember being blown away the first time I heard her voice on Breathe Me. And I love many songs she has written for other artists. I love great collaborations and to be given the opportunity to appear in the video while wearing my Heidi Klum Intimates collection, is definitely up there.
"Pedro and I had a blast shooting. You don't know exactly what's happening - but we're definitely up to something!"
It's not the first time Sia has collaborated with non-music celebrities - Shia LaBeouf starred in her Elastic Heart video.
The Fire Meets Gasoline promo will be released on VEVO and YouTube on Thursday (22Apr15).
