Apparently this is actually the case for the Lauren/Becky mix-up:
*****SPOILER. please everyone watch this. last night BB showed becky having a go at lauren over being moody then BB showed lauren crying with luke A etc. BB edited last night to make it look like lauren was crying over what becky had said. this is in fact WRONG. lauren was crying over an argument she had with shievonne and if you watch this clip it will even show lauren sayin 'shes 29' and luke A saying 'she might go tonight anyway' they are clearly talking abour lauren. i wouldnt have known any of this, its only for a man on a forum talking about it that i do. im complaining to big brother as bex got loadsa **** last night for how lauren reacted. IM FURIOUS!!! this shows how much of the show actually is edited!!!!
