13-year-old rapper Leondre Devries from Port Talbot is one half of Bars and Melody - the favourites to win the final of Britain's Got Talent 2014.
Here you can watch him - before he was famous - rapping and speaking to ITV Wales back in November 2012:
He and his brother Joseph were launching a campaign to fight bullying - and Leondre told our Correspondent Carl Edwards: "I just want to use my words and power to target bullying and stop it - that's my target."
Leondre and his friend Charlie Lenehan, from Bristol, wowed the judges in their first audition on the ITV talent show this year, with Leondre rapping about his experiences of bullying, and earning a golden buzzer from Simon Cowell.
That performance has now been watched 30 million times on YouTube.
