On this week’s Strong Heart episode, KARA’s Nicole revealed the story of how a male idol came up to her during “Mister” promotions and told her to eat less (or diet). Turns out this idol is none other than SHINee’s resident diva Key!

During the clip below, Nicole retold the story from 2:49, saying that there’s a “best friend” who’s a male idol and he bluntly told her “When are you going to lose weight?” Being hurt by this comment, Nicole talked back, “I’ll work out on my own so just wait and see!”

Then Super Junior’s Leeteuk added, “Maybe Nicole likes me that’s why she wanted to show me the good side of her.” Curiosity arose and MC Kang Ho Dong asked “Is he [the male idol] tall? Short?” (height in korean also sounds like “Key”). Hearing the repeated “Key” word, Kim Jong Kook answered “SHINee’s Key?”causing Nicole to burst out laughing and confessed that it was really Key. How nice of him.
