In March 2019, Kim revealed that her new album would be titled "9" and added "There's a lot of meaning behind that." Later that month, she announced that the album would be released on May 17, 2019. After a minor setback with her record label, eOne Music, that caused the album not be released on the original planned date, the project was postponed. On September 27, 2019, Kim released a second single titled "Found You" featuring City Girls and O.T. Genasis. The album later became available for pre-order on all digital-download platforms on October 4, 2019 (along with the track "Pray For Me" featuring Rick Ross and Musiq Soulchild) with a release date set for October 11, 2019. Upon its first week of release, the album charted on the R&B/Hip-Hop and Rap Album Sales, Digital Albums, Top Albums Sales, Independent Albums and Rap Album Sales. During one of the reunion episodes for "Girls Cruise", Kim revealed that the album would be a two-part project, stating "I recorded so many songs. I have a part one and a part two." She also shared that her co-star and Instagram comedian Vena "Pretty Vee" Excell will make an appearance on the record. In October 2019, Kim revealed that she will have a collaboration with Missy Elliott and Paris Hilton on the follow-up to "9". In an interview with Radio 103.9, Kim confirmed that the City Girls would be involved with the follow-up to "9". She also stated that she would "love" to have Pretty Vee host her tour. On her November 8, 2019 appearance on "The Real", Kim again confirmed that Paris Hilton and Missy Elliott will appear on "9"s follow-up; she said the song "sounds like a classic Missy Elliott record but 'now.'"(1:20)
