Melanie C Releases “Undefeated Champion?”

Fresh from the euphoric momentum of her forthcoming ninth studio album Sweat, Melanie C returns with a powerful new single, “Undefeated Champion,” alongside the announcement of her upcoming Melanie C World Tour.

A bold, uplifting anthem about resilience and inner strength, “Undefeated Champion” continues the joyful, club-ready spirit of the Sweat era while delivering one of Melanie’s most empowering messages yet. 

The release arrives alongside the announcement of The Melanie C World Tour, a global run of shows bringing the high-energy spirit of Sweat to fans worldwide. The tour kicks off in North America, starting in Montreal on September 8, with stops in Toronto, Washington, D.C., New York, Boston, Chicago, Vancouver, Seattle, San Francisco, and Los Angeles, before concluding in San Diego on September 25. Melanie will then head to the UK and Europe in October, followed by Asia and Australia in November. Known for her electrifying live performances, she’ll celebrate both her pop legacy and her evolution as a DJ, delivering a set that blends euphoric dancefloor energy with the iconic hits that have defined her career.

Before she became Melanie C of the Spice Girls, she was Melanie Chisholm of “The F**king Yeah Four”, a group of 18-year-old friends dancing through the Costa Brava rave scene in the early ’90s. Those nights of breakbeats, sweat and freedom would shape her forever. Decades later, Melanie C channels that same raw energy into Sweat – her ninth studio album and most euphoric record to date. Recorded between London, Stockholm and LA, Sweat is a celebration of joy, movement and community – a fusion of Melanie C’s pop legacy and her more recent evolution as a DJ. “I’ve done a lot of soul-searching,” she says. “Now I just want to have some fun and get people dancing again.”

The new single lands amid a standout period for Melanie C. Recent highlights include headline performances and appearances at ABC Sydney New Year’s Eve, New York’s Jingle Ball, appearances on The Kelly Clarkson Show and Good Morning America, plus viral moments alongside global pop phenomenon KATSEYE. Melanie was recently named Apple Music’s featured artist for their ‘Music That Moves Me’ playlist series, as part of their January fitness activation.
