A lot of people may not know that WILLIE NELSON is skilled in the martial arts. He's been doing it since he was a kid and has studied Judo, Kung Fu ... and has a black belt in Tae Kwon Do.
These days he practices the Korean art of Gong Kwon Yu Sul, and he'll be getting his fifth-degree black belt in that discipline on April 28th, which is the day before his 81st birthday. (Feeling like a slug? Me too.)
