Heidi Klum burns up lingerie campaign video featuring Sia's 'Fire Meet Gasoline'

Model Heidi Klum released a video on Thursday, April 23 in honor of her new lingerie line featuring music from Australian singer-songwriter Sia. In the hot and heavy clip, Klum gets cozy with Game of Thrones actor Pedro Pascal to "Fire Meet Gasoline."

"Fire Meet Gasoline" is one of the standout tracks on Sia's most recent album, 1000 Forms of Fear. Over producer Greg Kurstin's haunting production, she sings about a consuming romance in clever wordplay. "Strike the match, strike the match now / We’re a perfect match, perfect somehow,” Sia sings. "Fire" burns with a dark intensity brought to life by the singer-songwriter's passionate performance.

Unlike past songs "Chandelier," "Elastic Heart" and "Big Girls Cry," Sia clarified that "Fire Meet Gasoline" was not a single from 1000 Forms of Fear. She only lent the track to Klum's lingerie campaign video.

"Fire meet gasoline is not an official music video, nor is it my new single," she wrote on Twitter. "It's a lingerie commercial to which I licensed a song."

In honor of the Heidi Klum Intimates campaign, the model released this special video featuring Sia's "Fire Meet Gasoline." Klum wears the line throughout much of the clip and gets hot and heavy with actor Pascal. Their twisted romance culminates in burning down a house and stealing a blonde Sia wig. Fashion photographer and Lana Del Rey's rumored beau Francesco Carrozzini directed the sexy and sizzling video.

"Fire Meet Gasoline" is now available on iTunes. Sia's 1000 Forms of Fear album became her very first to debut at no. 1 on Billboard when it was released last year. After penning hits for other artists, 2014 became a breakout year for the reclusive singer. She is currently readying her next record tentatively-titled This is Acting.
