"Ugly Heart" is the second single by American-British-Canadian girl group G.R.L. from their self-titled EP. The song features songwriting credits from Ryan Baharloo, Ester Dean, Lukasz Gottwald, John Charles Monds and Henry Walter, with production credits from Gottwald and Walter under their production monikers, Dr. Luke and Cirkut. The song was released on June 3, 2014, as the lead single from the EP. "Ugly Heart" is a guitar-driven dance-pop song that also incorporates a ukulele. The track centers on a man who initially appears beautiful on the outside, but later displays his ugly side. The group thought a lot of women would be able to relate to the song and hoped it would inspire them to find someone who would treat them well. The song was met with general acclaim from critics. The song's accompanying music video was directed by Chris Marrs Piliero. It depicts the girls being arrested by the police, after they tattoo the word "ugly" on a man's face (Andrea Denver). It was watched 2.5 million times in less than a week following its release. "Ugly Heart" was the last single to be released by the group before band member Simone Battle's death on September 5, 2014. The song received renewed interest in October 2016 when British girl group Little Mix released their lead single "Shout Out to My Ex", from their fourth studio album Glory Days. Some people said that the choruses of the two songs had similarities.
