Although the Joo Yeon fans in the house probably know this by now, don't get your panties in a bunch - Just wanted to share this for the people who didn't know that After School member Lee Joo Yeon has had some experience in the acting field!
Joo Yeon was spotted as a Japanese waitress in the following scene in 2007 K-Movie My Tutor Friend Lesson II which starred Park Ki Woong and Lee Chung Ah. For someone who normally looks so cute and innocent, I couldn't believe she was able to fit the role so well. With all that makeup on, I couldn't even recognize her! Here's the scene and some screenshots from the movie.
