Big Brother producers say they have been hunting for 'new faces' to appear in this year's series.
While Big Brother typically launched in June on Channel 5, this year's show has been pushed back.
Celebrity Big Brother instead kicking off the summer season, launching last week and concluding tonight (September 10).
Big Brother will launch at the end of the week on Friday, September 14.
Speaking to BBSpy, Paul revealed that the show's team were actively trying to find 'complete unknowns' for the non-celebrity series.
Recent series have included familiar faces that had already appeared on reality TV, including shows such as Ibiza Weekender and Ex On The beach.
It was also announced that the upcoming Big Brother would have a completely separate identity from the upcoming Celebrity Big Brother and it's 'eye of the storm' theme.
Sources previously claimed that the 2018 run would see a 'back to basics' refresh.
An insider told the Daily Star on Sunday that the series will ditch "manipulative tasks" and allow drama to unfold "naturally".
They explained: "They want it to be a true social experiment because they realise they have lost that element along the way."
One thing not cleared up yet is the future of the show.
Currently both Celebrity Big Brother and Big Brother are set to end their current contracts with Channel 5 at the end of 2018.
The channel has yet to announce its decision on whether or not to renew the contract.
Although reports have claimed the shows will be dropped, a spokesperson for Channel 5 said: "The situation remains unchanged; Big Brother is currently contracted until the end of the year, there’s no update on future series beyond 2018."
