Key Points
- Geri Halliwell visited rehearsals, gave advice on chemistry and staying present, and surprised them with gift bags

DECEMBER 10 just got a major pop stamp of approval: Geri Halliwell is officially a fan.
The rising boyband, formed on Simon Cowell’s Netflix series The Next Act, revealed that the Spice Girls star recently dropped by rehearsals in West London and left a big impression on the group.
According to the band, Geri attended with her stepdaughter after missing one of their London shows.
Members Danny, Sean and Hendrick told The Sun they were stunned to meet the pop icon, describing Halliwell as full of energy and generosity.
The singer reportedly shared advice about staying in the moment, keeping their group chemistry strong, and enjoying the journey as their fame grows.
She also surprised the band with gift bags, including portable speakers they say they still use.
December 10 — made up of Cruz, Danny, Hendrick, Sean, John, Josh and Nicolas — has been building serious momentum since breaking out on The Next Act. The group recently released their single “Angel” and continues to attract a fast-growing fanbase online.
The band also shared that Simon Cowell was proud of their sold-out London show at O2 Academy Islington, especially their use of live instruments. Cowell and Lauren Silverman were both in attendance.
Fresh off their first Brit Awards appearance, December 10 said the whirlwind still feels surreal. But with support from both Cowell and a Spice Girl, the group’s next chapter is looking brighter than ever.
Why This Matters
Geri Halliwell’s surprise support — paired with Simon Cowell’s ongoing backing and a sold-out London show — gives December 10 mainstream credibility, mentorship and media momentum that could accelerate their crossover from reality TV breakout to lasting pop act.
