Celebrities heading into the Big Brother house have apparently insisted no cameras are installed in the bathrooms.
The stars of the new series in January - rumoured to include ex-Sugababe Mutya Buena and glamour girl Lucy Pinder - are determined to keep their toilet time to themselves, reports The Sun.
So Celeb BB bosses have agreed not to film in the loos and have altered a see-through wall which would've let the contestants peek at their housemates in the bathroom.
"The one thing they have all asked is that no cameras go into the bathrooms - and that the wall is covered up, which we have now done," said a source.
It has previously been reported that Cliff Richard turned down the chance to go on the reality TV show - because bosses wouldn't give him a private toilet.
Other stars rumoured to be entering the reality TV compound include actor Verne Troyer and former Liberty X singer Michelle Heaton.
Celebrity Big Brother starts on January 2.
