Heidi Klum and "Game of Thrones" fan favorite Pedro Pascal get very hot and heavy as arsonists in a new music video with Sia called "Fire Meet Gasoline. According to the singer on her Twitter account, the new video is "not an official music video, nor is it my new single. It's a lingerie commercial to which I licensed a song."

As it turned out, E! News noted that the video was in fact a campaign by Heidi Klum for her new line of intimates, and she has commissioned Sia for the song to the lingerie-filled clip, featuring herself and the "Game of Thones" star.

This certainly clears up the issue on why 12-year-old Maddie Ziegler isn't in this one video. After all, Zeigler has been the staple in Sia's videos as an interpretative dancer. Her most recent collaborations include the often-spoofed video of "Chandelier" and the very controversial one with Shia LeBeouf, "Elastic Heart," which many claim had a lot of pedophiliac overtones, as reported by News Australia.

This one is different. As Huffington Post noted, Klum and Pascal look all loved-up in the video, rolling in the grass and kissing in bed in a clip that definitely screams lingerie ad, more than a music video.

In a statement made by Klum regarding her collaboration with the singer, she said, "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. [Director] Francesco [Carrozzini], Pedro and I had a blast shooting. You don't know exactly what's happening - but we're definitely up to something!"

And of course, as a nod to the singer who gave the track for the campaign, Klum dons Sia's iconic platinum blonde wig as she walks away from the house she doused with gasoline and lit on fire, to the arms of Pascal, who was waiting for her by a truck.
