Duff uses Olsen to blast teen pressure

Teen singer Hilary Duff has blamed the intense pressure heaped on young stars for causing TV rival Mary Kate Olsen's battle with anorexia.

At 16, Duff is two years younger than Olsen - who last month checked into a clinic to be treated for the eating disorder - but the So Yesterday star can already empathise with her, because she's fully aware of the demands forced on rising talents to look glamorous.
