Blue Peter features star Radzi back at school in Newport
[gallery] He has competed in skeleton bobsleigh, been a semi-finalist on Gladiators and is now living his dream as a TV presenter.
Blue Peter's newest star Radzi Chinyanganya last night gave viewers a glimpse into his childhood – including his seven years at Adams' Grammar School in Newport.
The episode of the long-running BBC children's show focussed entirely on 26-year-old Radzi, who hails from Wolverhampton.
Viewers got a look into Radzi's childhood with his Scottish mother and Zimbabwean father. And the cameras were given access to Adams' Grammar School as Radzi returned at the end of last year.
The enthusiastic presenter was shown reuniting with design and technology teacher Andy Jones, who led Radzi and his team when they won the Astrazeneca Young Designers Award in 2005.
Radzi joked that classmates didn't want his autograph when he was in school – but there were plenty of Adams' pupils asking for it on his return.
Radzi said: "I wanted to be a Blue Peter presenter since I was 10. I used to ask people whether they wanted me to sign their homework diaries so that they could sell it when I became a famous presenter, but not many of them took me up on the offer.
"Now I am a Blue Peter presenter, people sometimes want it."
