2026 is set to be a huge year for British girl group XO as they gear up for the release of their debut mini-album, Need To Know, on October 16.

After forming in 2024, XO released their debut single, Lovesick, in September 2025. The following month, the group added another notch to their belt with Real Friends, co-written by Charli XCX, which was hailed by TotalNtertainment as a ‘swaggering and empowered electro-pop anthem’. The Clique hitmakers are carrying that momentum into 2026 as they prepare for an appearance at All Points East in August, followed by their own headline tour with a stop at the O2 Academy Islington in November. Although they have already drawn comparisons to fellow girl groups such as the Spice Girls and KATSEYE, XO are carving out their own path and are certainly ones to watch in 2026.
