I agree, overrated, wouldn't look twice at a girl like that in the streets. No real tits (would take saggier, bigger tits over her 'pert' ones that would probably be conical topless).
Other ugly celebs that people wrongly admire/idolise:
Rihanna
Lady Gaga
That weird looking one in girls aloud
The guys in One Direction - normal kids with expensive hairdos.
F*CK mass culture and the ignorance it produces
