Unfortunately the genie is out of the bottle re 'reality stars' (not real and certainly not stars) lowering the tone of Celebrity Big Brother.........their image and reputation is so low rent that people who are entitled to call themselves celebrities won't go near CBB for fear of association and you can't blame them.
C5 should have tried to keep up standards and insist that anyone who is on CBB can genuinely regard themselves as being recognisable for having a talent in in their field TV,Film,Sport,Music or being genuinely well known in public life.( politics,media,business etc)
Gormless, embarrassing ten-a penny 'reality' morons need not apply.
