"Bad Romance" is a song by American singer-songwriter Lady Gaga from her third extended play (EP), The Fame Monster (2009)—the reissue of her debut studio album, The Fame (2008). Following an unauthorized demo leak, Gaga premiered the final version of the song during Alexander McQueen's 2010 Paris Fashion Week show in October 2009. Written and produced by Gaga alongside Moroccan-Swedish record producer RedOne, "Bad Romance" was released as the lead single from The Fame Monster on October 19, 2009. Musically, it is an electropop and dance-pop track with a spoken bridge and a hook featuring nonsense syllables. Inspired by German house and techno music, the song was developed as an experimental pop record. Lyrically, Gaga drew from the paranoia she experienced while on tour and wrote about her attraction to unhealthy romantic relationships.
