In the 'Best Friend Special' of 1 Night 2 Days', actor Lee Sun Gyun showed a picture of his two children for the first time on television. In a mission where he had to find his own way to the cast's base camp in Kyungpo, Lee Sun Gyun successfully hitchhiked a ride from a couple going to the same location. During the car ride the couple asked him if he had any children. He replied he had two kids and revealed a never-before-seen photo of his two boys ages 24 months and 4 months old. Clearly a proud father, he boasted, "It's the world's most important photo to me. Isn't it beautiful?". Meanwhile, this 'Best Friend Special' also features Jang Woo Hyuk, Lee Seo Jin, Lee Geun Ho, and Jang Soo Won. Part two of this special will show the boys going against each other as they play a variety of sports. Source + Image: Sports Seoul
