Lee Joon revealed his inside scoop on losing the role of F4.

On the 22nd broadcast of MBC 'Radio Star' Jay, Lee Joon, Uee, and Im Shi Wan made their appearances to show off their wit.

Lee Joon opened up about almost being a star of F4. He commented "even before the roles were assigned I was a big candidate but the plan was for me to star in 'Ninja Assasin' then go on to film 'Flower Boys' in Korea."

However, because he had to shave his head for Ninja Assasin Lee Joon had to kiss a role as F4 good-bye. Though he even tried to wear a wig, it was too obvious so he had to it the role go to someone else.
