Tickets priced from €42.70 including booking fee & €2 restoration levy on sale now with  Ticketmaster Ireland 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. Speaking about the new single, Melanie C says: “‘Undefeated Champion’ is about getting knocked down and choosing to rise every single time. It’s a reminder that the hardest moments are the ones that make us stronger. It’s faith over fear, joy in the face of adversity - almost challenging the universe: ‘come and have a go if you think you’re hard enough!’ At its core, it’s about realising we’re far more resilient than we think.” The release arrives alongside the announcement of The Melanie C World Tour, a global run of shows set to bring the high-energy spirit of Sweat to fans around the world, including a headline show at the O2 Academy Brixton on October 23rd, 2026. Known for her electrifying live performances, Melanie will 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. Fans will have multiple opportunities to secure tickets in pre-sales and the general sale which will go live on Friday, March 20th, 2026 @ 10am local time. Full tour dates and ticket details below. Before she became Mel 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.
