"How to Be a Heartbreaker" is a song written and performed by Welsh singer-songwriter Marina and the Diamonds taken from the US Edition of her sophomore album, "Electra Heart". The song was written a week after finishing the UK version of the album, and therefore does not appear on that edition, but is featured as track 12 on the US version. It is due to be released as her fourth UK single from Electra Heart and her second international single. Marina confirmed to Digital Spy that 'How to Be a Heartbreaker' will be released in the UK on 15 October 2012, however this turned out to be untrue. On 1 November 2012, Marina confirmed via her Twitter page that the release date for the audio single 'How to Be a Heartbreaker' in the UK is 16 December 2012. On 22nd November 2012, Marina stated via her Twitter page that the UK release of the song would be delayed until Spring 2013, because of her US tour in December.
