Chris, 60, has been in a relationship with Charlotte Corney, the owner of the Isle of Wight Zoo, for over a decade. However, they are not married and sadly live miles apart due to work commitments - Chris lives in the New Forest while Charlotte is based on the Isle of Wight.
They two met in 2007 when Chris visited the zoo to film a programme and struck up a romance shortly after. Speaking about their relationship, Charlotte previously told Radio Times: "Chris and I met professionally when he visited the zoo that I run on the Isle of Wight. He tells me now that he knew that day that I was The One."

Michaela met cameraman Nick in 2003 while filming in the South African capital two years after her divorce from filmmaker Duncan Chard, who she wed in 1996. Nearly twenty years later, Michaela and Nick are the picture of romance, something Michaela puts down to their decision not to follow tradition. She told The Mirror in 2018: "I think the secret is not to get married."
