“Bad Girl” is a song by Canadian singer Avril Lavigne for her fifth studio album, Avril Lavigne (2013). It was written by Lavigne, Chad Kroeger and David Hodges, while the song was produced by Kroeger and Hodges and features guest vocals by American singer Marilyn Manson. After hearing “Bad Girl”, Lavigne thought Manson would complement the track. Manson added his vocals to the song early one morning, and Lavigne was honored to be able to collaborate with him.
A nu metal and pop song with industrial rock, glam rock, and 1970s punk rock elements, “Bad Girl” is about BDSM and erotic asphyxiation. Critics felt it was a departure from Lavigne’s previous work. Upon its release, “Bad Girl” received mostly positive reviews; some critics complimented its energy while others found it nightmarish or disgusting. The song charted at 58 on the South Korean’s Gaon Chart and at number 88 on Billboard’s Canadian Hot 100. Lavigne performed “Bad Girl” during The Avril Lavigne Tour.
