Celebrity Hijack was a spinoff of the popular reality show, which aired on E4 and featured especially talented youngsters ranging from 18-21 years old.
Ogogo finished fourth in the final. The series was won by aspiring politician John Loughton.
The Lowestoft middleweight dedicated his Olympic victory to his mother, who suffered a brain haemorrhage six weeks ago. "Hopefully I've given her a boost and it will help in her recovery," he said. Meanwhile, his sister Leanne went into labour on the same day as his London 2012 debut.
Ogogo will face Ukrainian Levgen Khytrov, the world champion and No.1 seed, in the next round.
