Singer Lee Chan-won, 27, revealed the unexpected reason his mother is a fan of the broadcaster Song Eun-yi, 50. On the 17th, YouTube channel VivoTV posted a video entitled "Lee Chan-won appears!" As a son of the National Singing Contest. Song Eun-yi and Kim Sook (48) appeared four times in the "National Singing Contest" and tried to make a phone call to Lee Chan-won, who won all the awards, in response to questions about honey tips for qualifying for KBS 1TV's "National Singing Contest." When Lee Chan-won answered the phone, Kim Sook laughed as if he was embarrassed, saying, "It's a big hit. I didn't have your number." Kim Sook and Lee Chan-won have been appearing together on JTBC's "Tokpawon 25 o'clock" since February. Lee Chan-won said, "You did not have my number? I contacted you like that." Kim Sook asked, "But why do you have your number?" Lee Chan-won replied, "I had a lot of programs with my sister," and Song Eun-yi said, "Sometimes I contacted you. I have a number to contact intermittently and I do not have a number to contact you often. " Lee Chan-won confessed, "My mom's favorite Celebrity is Sister Song Eun-yi." Kim Sook wondered, "Is it true?" And Song Eun-yi, feeling better, shrugged. But when asked why, Lee Chan-won replied, "Oh (with my mom) I have the same age" and made it into a laughing sea. Lee Chan-won later commented on the "National Singing Contest" tip, saying, "You have to win unconditionally. It's 100% exciting."
