Redknapp has quickly become a favorite in the jungle after a weekend of tasks and admirable behaviour.
The former football manager took the bushtucker trial to help win the camp food.
But he seems to have revealed little information as to why he went into the jungle in the first place.
Impersonating his home life while half topless in the camp, he said: "Sand, where's my shirt? I've got to go. I've got to go and do this stupid thing. "
Redknapp, speaking to himself and impersonating his wife …
"What do you do that for?"
Harry back as himself
"To get a few quid"
Redknapp is now the favorite bookies to win the show after impressing fans.
The 71-year-old starred alongside TV presenter Noel Edmunds in one of the best Bush Tucker trials yet.
The pair has a number of disgusting dishes including sheep's brain and beach worms.
His son Jamie Redknapp admits he's been overwhelmed by the response.
"I've been struck by the overwhelming support for my dad since he went into the jungle," he wrote in his column with the Daily Mail.
"Football is such a tribal sport but it feels like everyone has got behind him.
"Wherever I go, it's the first thing I'm asking: 'How's your dad?'. Soon followed by: 'Do you think he can win it?' "
Former Liverpool and Spurs midfielder Jamie also revealed it's strange seeing his Dad in such a different environment as football.
"He's showing what a good company he is. . . and he gained plenty of new friends by putting himself on 'dunny' duty, "he continued.
"I've seen him animated on a touchline as a manager, but watching him over the past week, I do not think I've seen him laugh this much in years. He looks like he's having the time of his life.
"It's a little strange to see him there. When we were growing up, Dad was never a great lover of a walk in the woods. He struggles to make a cup of tea too, but that does not seem to have stopped him here.
"He's gone to Australia with no expectations, and I'm glad that he's voted off first for his health, but now I really hope he can go all the way.
"He's gone from 10/1 to 4/5 ON with the bookies. But where he finishes will not matter.
"The first thing he'll ask Dec and Holly on leave will be: 'Who won the weekend?'"
