Reports claim characters have been scouted to star in this year's show, despite thousands of people sending in their audition videos in a bid to be a new hosusemate.
According to the Daily Star, a male porn star, a Dolly Parton fan and a singer with Tourettes claim they were approached to star on the Channel 5 series.
The report claims producers have been making direct contact with individuals and inviting them to take part.
But a spokesman for Channel 5 told the newspaper: "The casting of Big Brother is a confidential process."
Last month, it was revealed that Big Brother had been been renewed for a further three years.
Channel 5 extended its UK rights deal with Endemol Shine UK, meaning the channel will continue to broadcast two series of Celebrity Big Brother and one series of Big Brother each year.
