A rep from the program said on March 9 that she will be filming for 'Tutoring Across Generations' with Lee Jae Hoon, who had previously been partnered up with Lee Tae Im, on March 10 on Jeju Island!
The rep said, "Kim Nam Joo is not Lee Tae Im's replacement. She will be filming with him in order to support him rather than to participate in the diving experience. We are currently in discussion over whether Namjoo's appearance will be a one-time thing or she'd become a regular participant."
Meanwhile, 'Tutoring Across Generations' aired on March 9 without the diving portion.
