"Hotter Than Fire" was written by Eric Saade, Jason Gill, Devin Tailes, and J-Son.

[1] The collaboration with Dev started after Saade saw the video of her single Bass Down Low.

Dev heard an early demo of Hotter Than Fire and said immediately yes after they asked her if she wanted to join the song.

I love electro-pop and I feel like I'm in the middle of the development to begin to find what I want to do.

Idolator wrote that the song is "a blazing dance-pop jam" and compared it to Usher's "DJ Got Us Fallin' in Love".
