Hot and heavy, indeed. Heidi Klum is steaming up the screen opposite Game of Thrones hunk Pedro Pascal in a new video set to Sia's "Fire Meet Gasoline." 

Directed by Emmy nominee Francesco Carrozzini, the beautifully shot clip finds Klum in the throes of a steamy romance with Pascal. Throughout the first part of the song, the lovebirds are seen holding hands, making out, and rolling around a grassy knoll peppered with picturesque trees.

Things take a turn from there, though, as Klum — showing off her runway-ready bod in her Heidi Klum Intimates line — lights a match and sets fire to the very home where she and Pascal shared some of their sexiest moments.

Interspersed with scenes of the house going up in flames are shots of the couple steaming things up between the sheets. There's also a twist or two involving a bloody rock and Sia's trademark blonde wig.

"I am a huge fan of Sia's so it was an honor to appear in her new video," Klum tells Us. "Francesco Carrozzini shot the video, and Pedro Pascal and I got to play love interests. Even though the video has scenes that appear hot and steamy, the majority of takes ended with us in full laughter...Francesco left a lot of our giggling fits on the editing room floor."

She adds: "Pedro is an absolute sweetheart — such a kind man and, as any Game of Thrones fan will attest, an extremely talented actor. I was thrilled that he was able to costar in the video. I felt truly lucky to have the opportunity to work with him."
