The singer, who is planning to set up a deer farm in Scotland, wants to document his country life with girlfriend Chloe Tangney in the style of fly-on-the-wall shows produced by former glamour model Katie Price and her ex-husband Peter Andre.
Gill tells Britain's The Sun newspaper, "I might have a Katie and Peter-style reality Tv series. It would have to be right for me. My aim is to set the farm up as a business, and everything after that has to be right for myself, my girlfriend and my family."
The British boyband performed its last ever gig on 22 December (13).
