Bateman, who appeared in the very first series of Big Brother in 2000, suggested on his official Twitter account that the show could return to TV screens as early as August 17.
He wrote: "Looking forward to the start of CBB and BBLBC on 17th/18th August 2011."
'BBLBC' stands for 'Big Brother's Little Brother's Cousin', a tongue-in-cheek show created by Bateman and Victor Ebuwa last year in the Ultimate Big Brother house.

Former Big Brother psychologist Jo Hemmings added: "And I've got the start of #CelebrityBigBrother as Aug 16th - least we're all in same week!"
Bateman then replied: "16th 17th 18th pick a date, anyhow, bblbc will broadcast on whatever date they have chosen (sic)."
Neither broadcaster Channel 5 nor production company Endemol has confirmed an official start date for the show.
