Nick, from Cirencester, also gave his advice to I'm A Celeb stars, saying: "Be nice to each other, be kind to each other and be supportive of one another. I was lucky I was in with Harry Redknapp, and Anne Hegerty.
"The loveliest crew. We talk all the time, we talk all the time on our WhatsApp group.
"So be kind to one another, be supportive. I think the audience actually like that. People think the audience like it when you row."
