Channel 4 dropped the format in 2010, after hosting the programme for a decade and making stars out of contestants such as Jade Goody, Craig Phillips and Brian Dowling.
Since moving to Channel 5, the show has helped the broadcaster regularly beat its rivals in the ratings.
Celebrity Big Brother has averaged over three million viewers during its two runs, while the classic series last autumn picked up over 1.7 million viewers on a regular basis.

Frankie Cocozza, Denise Welch, Paddy Doherty and Jedward have been among the stars who have entered the famous compound, since its switch of broadcasters.
Channel 5 announced last month that it had already negotiated a deal with Endemol to broadcast an extra celebrity edition of the show in the autumn as part of its original two-year deal.
Brian Dowling, Emma Willis and voiceover legend Marcus Bentley are all signed up to continue hosting the main programme and spinoff series Bit On the Side.
