Auditions for the thirteenth series of the reality series took place earlier this year in London, with it being widely reported that the housemates would be moving in come May.
But according to Big Brother narrator Marcus Bentley, the show will now not be hitting screens until June.
It means that the nine-week stint will also clash with the launch of the Olympics, which start on July 27.
Asked by fans on Twitter when the series would be back on the air, Geordie Marcus revealed: "June - can't wait !
He added to another user: "No exact date yet Wendy - but it'll be June."
