As No Hong Chul and Jang Yoon Joo's virtual marriage has been catching much attention, Jang Yoon Joo's past photo shoot pictures have also been catching much attention.

In the pictures, Jang Yoon Joo showed off her perfect body through an underwear photo shoot.

Jang Yoon Joo had come out on an entertainment program last month and said that the secret to her body is checking her weight more than twice a day.

She said, "I weigh myself when I wake up in the morning and before I go to sleep at night. Crazy enough, when I check my weight, I can see what I ate and what I did that day."
