Bosses at the network are set to be convinced by the fly-on-the-wall show, which will be a guaranteed ratings hit, reported Daily Star.
"Producers have met with the band's representatives and it's pretty much a done deal. Details are being ironed out, including budgets and when to film," a source said.
According to the series' format, cameras will follow the every move of band members Harry Styles, 19, Louis Tomlinson, 21, and 20-yearolds Zayn Malik, Niall Horan and Liam Payne.
The bands' recent documentary movie 'This Is Us' proved a huge box office hit and ITV chiefs are hoping for something similar by securing the lads for a ten-week run.
