"I Fell in Love with the Devil" is a song by Canadian singer-songwriter Avril Lavigne and is the third track from her sixth studio album, Head Above Water. It was written by Lavigne and produced by Lavigne and Chris Baseford. The song is about a toxic relationship she maintained while suffering from Lyme disease. It was released as the fourth and final single from the album on June 28, 2019. It received controversy and backlash from Christian fans due to its image of the promotional art, and the lyrics of the song. Background and release On February 7, Avril wrote about the song: "Sometimes your heart conflicts with your head and leads you into situations that you know aren’t right and then once you're there, it's very difficult to get out. I also produced this song with Chris Baseford." "I Fell in Love with the Devil" is about being in a toxic relationship and was announced as the fourth single and officially the second single from the album on June 7, 2019. Critical reception In a review of Head Above Water, Arielle Gordon of Pitchfork said "Unfortunately, many of the statements she makes are, by contrast, stale and uninspired. Even in its strongest moments, there is nothing revelatory in the lyrics, which have a tendency to run out of steam. The worst offender might be 'I Fell in Love with the Devil', which recounts the story of a wayward lover with metaphors that seem plucked from a LiveJournal entry". Spins Zoe Camp was also unfavorable in her review, stating that Lavigne took a "technically slack (read: bored-sounding) stab at soul on 'I Fell in Love with the Devil'" and offered a "not-hot take on an abusive relationship". Alexandra Pollard of The Independent was more positive in her review of the song, claiming "Lavigne's voice reaches new heights too–particularly on 'I Fell in Love with the Devil', an ominous, tightly crafted rumination on toxic relationships". Rolling Stones Emily Zemler labelled it an "emotive anthem" and a "heartbreak-tinged number", and went on to claim that "['I Fell in Love with the Devil'] is a much more emotionally-driven track than her previous singles, 'Head Above Water' and 'Dumb Blonde'". Commercial performance "I Fell In Love with the Devil" did not debut on the charts anywhere, the song was certified Gold in Brazil with 20,000 units sold. Music video A music video for the
