Background and development

During an interview at the Billboard Women in Music event on March 31, 2025, Mariah stated that her fourth studio album had been completed. ^[1] On July 8, 2025, Mariah announced her album, Hearts Sold Separately, with a release date of August 22, 2025. ^{[2] [3]} The announcement was accompanied by reveal of the album artwork—a miniature green toy soldier against a pink backdrop—symbolizing the album's concept as "the war on love" and the emotional battles inherent in relationships. ^[4]

Release and promotion

Hearts Sold Separately was made available for digital pre-save on July 9, 2025, through major streaming platforms. ^[5] CD and vinyl versions, including standard and autographed editions, were simultaneously opened for pre-order through her and Epic Records' official merchandise stores. ^[4] Following the album's announcement, a headlining tour, Hearts Sold Separately Tour, was announced July 15, 2025, with dates spanning North America beginning in September 2025. ^[6]

"Burning Blue" was released on May 2, 2025, as the album's lead single. Produced by Jetski Purp and Nineteen85, the song is an R&B song that employs elemental imagery—most notably the contrast of "cold as ice" and "fire"—to illustrate the tension between emotional detachment and intense longing. ^{[7] [8]} The single debuted at number 25 on the US Billboard Hot 100, marking Mariah's second chart appearance and her highest-charting song in the country. ^[2] A music video for the song was released on May 10, 2025, and depicts Mariah singing the song while backed by a troupe of war-ready dancers. ^[9] On June 2, 2025, Mariah performed the song on Jimmy Kimmel Live!. ^[10] She later performed the song at the fifth annual Beauté Noir Festival on June 21, ^[11] followed by a performance at the 2025 Essence Festival of Culture on July 5. ^{[12] [13]}

She released the album's second single, "Is It a Crime", featuring Kali Uchis on July 31, 2025. ^{[14] [15]}
