Minor celebrities are fuelling a culture of 'high heels and low IQs' in which girls abandon intellectual endeavour in favour of pursuing fame, headmistresses have warned.
Dazzled by superficial glitter, girls increasingly aspire to be footballers' wives or girlfriends and overlook the importance of good character and achievements in their own right.
The claim by members of the Girls' Schools Association, representing top girls' private schools, came as a survey of 1,000 parents found they felt WAGs were the worst influences on girls.
They were ranked lowest in a list of 12 influences on daughters, just behind 'It Girls', reality TV stars and celebrity magazines.
The best influences were considered to be family, friends, teachers, Olympians such as Rebecca Adlington and businesswomen.
The survey, which also found that almost half of parents are forced to discuss image and appearance with their daughters 'often', coincided with the launch of the GSA's advice website aimed at parents of girls.
At the launch of the site, Pat Langham, head of fee-paying Wakefield Girls' High School and a former GSA president, sounded a warning over the growing influence of celebrity culture.

'Parents are trying to inculcate in their daughters a strong work ethic and principles, and anything which leads them to believe marrying somebody or becoming somebody's girlfriend is what their aim in life should be demeans them and diminishes them,' she said.
'If they believe that having cosmetic surgery, hair extensions and a good handbag will bag them a footballer and therefore fulfil their career aspirations, then they need better career aspirations.
'When I talk to the girls in my school, they see through the facade and sometimes see people with very high heels and quite low IQs. But not all have got those powers of discrimination.'
Jill Berry, the new president of GSA and head of Dame Alice Harpur School in Bedford, said: 'It is no surprise that parents felt WAGs and celebrities were more likely to be a negative influence than positive influence.
'I think it is the whole celebrity culture. You see wives and girlfriends who are famous because of their situation, not necessarily their skill and talent.
'If girls think to be rich and famous is to be some sort of goal, parents may consider that that's a less positive outlook than wanting to be successful in a recognised profession and make a career that will have a positive impact on people's lives.'
But she said that aspects of celebrity culture could be positive, suggesting that TV hospital dramas such as ER and Casualty may encourage teenage girls to choose careers in medicine.
The GSA's new website, mydaughter.co.uk, aims to bring together the wisdom of experienced headmistresses to help parents steer their girls through adolescence and beyond.
It will cover issues such as fulfilling girls' academic potential, dealing with bullying, eating disorders, social networking sites and friendships.
