Photos of IU for her 2013 Japanese calendar have been revealed.

The photos were recently uploaded on an online community board with the title "IU is so sexy". The photos showed a sexy side of IU that fans haven't never seen before which was quite a contrast to her cute, innocent image.

The calendar was titled 'New year's gift from IU/IU?ONE' and she posed in various sexy poses, smiling devilishly at the camera, wearing bright red lipstick while bearing a shoulder, and striking a daring pose with a fur jacket.

Upon seeing the photos, fans said, "Why is this released only in Japan? Sell this in Korea, too!", "She looks so pretty", and "She looks more mature and sexy, but she still looks cute".
