After a recent broadcast of Fuji TV's "Sakigake", Tiffany's eye-smile has become a popular topic. Tiffany's trademark killer eye-smile, her doll-like hairstyle, and sharp jaw-line have captured the hearts of many men, even in Japan.

Netizens who have seen the pictures commented,

'Tiffany's eye-smile is also very cute'
'You became prettier after coming to Japan, keke. It seemed fun on stage.'
'Legendary eye-smile 'Fany.'

Recently, SNSD has achieved the #2 spot on Oricon charts with their Japanese single, 'Genie'.
