Music mogul Simon Cowell's latest venture, the seven-member boy band December 10, has captured the public's imagination. Formed from over 1,000 auditions of hopefuls aged 15 to 19, the group is already generating significant buzz ahead of their first chart debut, with a debut music video released and a follow-up documentary in the works. Fans are keen to know more about the fresh-faced members, so here is a definitive guide to their ages, listed from the youngest to the oldest.
From Teen Talent to Group Dynamic
The band's creation was the central focus of the Netflix docuseries Simon Cowell: The Next Act. Cowell's explicit aim was to scout the country for young male talent with the potential to reach the stratospheric fame levels of One Direction. The final lineup, with ages spanning from 16 to 19, represents a blend of youthful energy and emerging maturity.
The Youngest Members: Nicolas and Danny (Age 16)
Nicolas, at 16 years old, is no stranger to the spotlight. His musical pedigree is impressive for his age, having finished as runner-up on The Voice Portugal in 2022 before going on to represent Portugal at the Junior Eurovision Song Contest.
Danny, also 16, discovered his vocal gift thanks to his aunt, who first encouraged him to sing at the age of eight. He attended the auditions alongside his close friend and future bandmate, Josh.
The Middle Ground: John and Josh (Age 17)
John, aged 17, was so determined to be part of Cowell's new project that he turned down a role in Paddington: The Musical to audition. He has been aware of his singing talent from a very early age.
Fan-favourite Josh, 17, provided one of the audition's biggest surprises. Despite his confident performance, he revealed he had only been singing seriously for the past two years before trying out for the band.
The Eldest Members: Seán, Cruz, and Hendrik (Ages 18-19)
Seán is 18 years old and has been singing since he was four, though it took him time to fully commit to pursuing his talent professionally.
Cruz, 19, brings a musical theatre background to the group, having played a young Michael Jackson in Motown: The Musical as a child.
The oldest member is Hendrik, also 19. During the docuseries, Simon Cowell himself labelled Hendrik the "big brother" of December 10, praising his calm and level-headed demeanour which stabilises the group.
With their ages officially confirmed, the countdown is on for December 10's next moves. The band's carefully constructed mix of youth and experience, from the 16-year-old competition veterans to the steadying 19-year-old influences, forms the foundation of what Simon Cowell hopes will be the next global pop phenomenon.
