How to Be a Heartbreaker

Diamandis explained that "How to Be a Heartbreaker" was the only new track on the US edition of her album Electra Heart, and she wrote it "as the UK album was being printed."^[2] Lyrically, she stated the song "basically involves four rules on how to be a heartbreaker. It's a guide for everyone!"^[2] Despite initially confirming to Digital Spy that "How to Be a Heartbreaker" would be released in the United Kingdom on 15 October 2012,^[3] Diamandis ultimately stated via her Twitter page on 22 November 2012 that the UK release of the song would be postponed until spring 2013 because of her US tour in December.^[4]

On 19 September 2012, Marina announced on her Twitter page that the music video for "How to Be a Heartbreaker" would premiere online on 24 September.^[5] However, problems occurred on the day of the supposed release, and Diamandis took to her Twitter to explain the situation: "So, someone at my record label won't let me release the video because I look ugly in it apparently and we need more money and time to paint out ugly parts. The video will be out end of the week. If not, I am happy to leak the 'minger' version for my fans."^[6] The video premiered on 28 September 2012 on YouTube.^[7] Marina also worked on the song for about 6 months prior to being released.

The video was directed by duo Marc & Ish and filmed in late August 2012.^[8][9] It opens with Diamandis in a shower surrounded by Speedo-clad male models. It includes various close-up shots of Diamandis and the models throughout the video. She also appears with four different men in various settings, each showing her with a different colored hair ribbon. It includes shots of her walking alone on the beach in some parts of the video, and includes a shot of her holding a platter with a severed and bloodied mannequin head. She dons black hair and various black dresses throughout the video, and her signature heart makeup on her cheek.

"How to Be a Heartbreaker" was released as the third single off Electra Heart. The song was a commercial success worldwide. In the United Kingdom the song peaked at number 88 and spent one week on the chart.^[10] The song ranks as Marina's fifth best-selling track to date in the United Kingdom, with 95,000 combined sales as of February 2019.^[11] "How to Be a Heartbreaker" was certified Silver in the United Kingdom in November 2021, denoting sales in excess of 200,000 units.^[12] In Denmark the song peaked at number 18 and was certified Platinum.^[13] The single was certified Platinum by the Recording Industry Association of America (RIAA) in June 2021.^[14]
