Although Lee Hyori seemingly has it all with her talent, visuals, and charms, she revealed that she was once jealous of fellow Fin.K.L member Sung Yuri. 

On the June 3rd broadcast of SBS Power FM's 'Cultwo Show', when asked, "Do you meet up with the Fin.K.L members often?", Lee Hyori shared, "Although I meet Ock Joo Hyun often, I haven't met up with the other members recently."

"In the past, Lee Jin and Sung Yuri had a rough time adjusting to acting but I feel good knowing that they are currently doing well in that field. I also think that musicals suit Ock Joo Hyun well. She was born with the visuals and voice to do musicals."

With the subject of visuals brought up, Hyori then talked about Sung Yuri's visuals, stating, "Honestly, I was jealous of Sung Yuri's visuals. Because she is pretty, she was the most popular among the male fans. Although I'm no longer jealous of her now, I think I was jealous of Sung Yuri's visuals back then."

Fans commented, "So there was someone that Lee Hyori was jealous of", "Sung Yuri really looks like a doll", and "Lee Hyori and Sung Yuri have totally different charms."
