If Cosmopolitan wanted to give readers a sexy December issue, then they are off to a good start. Kahi, the former leader of the massively popular K-Pop group, After School appears in the magazine in a seductive and eye-catching shoot.

The singer, who has recently embarked on a successful solo career as a musician with her new album "Who Are You?," is no stranger to making headlines for her looks. She takes over the magazine in total bombshell style. She also did fantastic work on "Dream High 2," and in the interview she talks about graduating from After School and her recent stint in America.

Sexy lace two piece.

It looks like she's in pretty good shape, and by pretty good we mean, are you taking perfect pills?
