Question: Given the following context:  After returning from the United States after the launch of her debut studio album The Family Jewels (2010), Diamandis considered creating a character which would become the centerpiece of her follow-up project. She commented that she was inspired by the "Tumblr generation" to photograph herself in several places across the United States, appearing as a different persona in each picture to mimick the anonymity of the "mini-stars of the internet". The final product became "a cold, ruthless character who wasn't vulnerable", which she later named "Electra Heart" and detailed as a tool to represent a combination of elements associated with the American Dream and Greek tragedy, and added that visuals would merge the differing concepts into a cohesive idea.Diamandis first announced Electra Heart in August 2011; it was initially planned to become a three-piece project inspired by American culture in the 1970s, although it eventually evolved into her second studio album. Diamandis originally planned to release the record as a "side project" under an entity separate from Marina and the Diamonds, although her management disapproved. The track "Living Dead" was the first recorded during its production, and approximately 22 songs were recorded for potential inclusion on the album. She later commented that the record was dedicated to "dysfunctional love", elaborating that "rejection is a universally embarrassing topic and Electra Heart is my response to that." Diamandis stated that Electra Heart was influenced by Madonna, Marilyn Monroe, and Queen of France Marie Antoinette; she described Madonna as being "fearless" and felt that she showcased a desire to be a successful artist beyond fame and wealth. Diamandis told Glamour that Britney Spears influenced a "double-sided" theme for the record of both "innocence" and "darkness". She described the final product as being "a bit cringe" and reflective of her personal experiences, although noted that its promotional campaign would be "pink and fluffy".  answer the following question:  What is the full name of the singer that created the character "Electra Heart"?
Answer:
Marina and the Diamonds
