Britain’s Got Talent 2025 auditions have always made waves online - and few know more about becoming an internet sensation than the ITV1 show’s newest judge, KSI.
Launching his current YouTube channel in 2009 at the age of 16, KSI - real name Olajide Olayinka Williams ‘JJ’ Olatunji - dropped out of school to pursue a full-time career creating video content for the social media platform, where he has amassed over 44 million subscribers, largely among the 13-28-year-old ‘Gen Z’ crowd.
