BARBIE-obsessed Blondie Bennett is taking her quest to become a doll to the extreme - using hypnotherapy to make herself stupid. The 38-year-old Californian has hypno sessions once a week to make her more easily confused and vacant. Blondie, who changed her name a year and a half ago, has had five boob jobs taking her to a whopping 32JJ. And she also uses Botox and lip fillers to give her a more artificial appearance. But to make the transformation into the plastic toy complete, she is training herself to become dumb.
