Mel C released her new single "Sweat" in October 2025, featuring a sample from Diana Ross’s "Work That Body." During a backstage interview at the iHeartRadio Z100 Jingle Ball, she described the track as a fresh blend of her pop roots and house music influences from eight years as a DJ, reflecting her artistic evolution. The song merges classic dance grooves with contemporary energy, marking a fun, authentic shift in her music. Amid the holiday season, she balances family time with her daughter in New York and UK traditions. The iHeartRadio Jingle Ball Tour will air as a special on ABC on December 17, 2025, with a Hulu release the next day.
