'Reborn Rich' actor Kim Young Jae appeared as a special guest on the latest episode of 'Radio Star' and shared some of the behind-the-scenes stories that took place on the set of the drama.

In the new episode of 'Radio Star' that aired on June 21, Kim Young Jae appeared as a special guest and revealed that this is the first time he has appeared on a variety program. The actor revealed that he decided to appear on the show and shared, "My first kid is in the 4th grade, and my second child is in the 1st grade. I only appear on dramas, so my kids aren't able to watch the work that I am in. They only watched 1 movie I was in, so I wanted to show them that I appear on television as my job and wanted to show them that I'm funny too."

In particular, Kim Young Jae shared his experiences filming the popular drama 'Reborn Rich.' He shared that he gained much recognition from appearing in the drama and explained, "People don't know my name but they know me as 'Song Joong Ki's dad'. After filming 'Reborn Rich,' my family went on vacation and the owner of our lodge recognized me and treated us well."

He also shared a behind-the-scenes story about Song Joong Ki and his wife. He shared that Katy Louise Saunders had visited the filming set often, but he thought she was a staff member.

Kim Young Jae shared, "The production team and cast members had dinner after the filming of 'Reborn Rich' ended. At that time, Song Joong Ki's dating news had been just released. So we found out that his wife had come to the film set a lot but no one knew (that she was his fiancé). She came so quietly and meshed so naturally with everyone, we all thought she was a staff member."
