# K–12 (album)

K–12 (pronounced "K through 12") is the second studio album by American singer Melanie Martinez. It was released with an accompanying film of the same name on September 6, 2019, through Atlantic Records. Martinez played the main character, "Cry Baby," in this film that she wrote and directed.

## Background

Martinez began writing the album in 2015. In a 2017 interview with Billboard, Martinez said that her then-untitled second album was finished and would be accompanied by a film that she was writing and directing. In a February 2019 Instagram post, she wrote that the album "had been done for like two and a half years now", that it would likely be released at the end of summer and that no singles would be commercially released before it. however, on an Instagram story in January 2020, Martinez revealed that “Lunchbox Friends” would be the album's lead single.
On January 7, 2020, Martinez announced through her Instagram stories that she would be releasing an EP titled After School that is attached to K–12 and will also be released as the extended deluxe. She originally planned to release the project in the spring of 2020, but the project ended up being released on September 25, 2020. Martinez also revealed that she had planned two more films, both of which were supposed to be accompanied by albums however, both were scrapped due to Martinez’s decision to close the Cry Baby storyline, and because the projects would be too expensive to create.
