Gil failed the mission to get Lee Hyori to call him "sexy" on the latest episode of 'Infinity Challenge'.

The team went on a challenge to fulfill the tasks of a bingo game and Gil was given the mission to hear a specific phrase from someone. Gil hinted on his cameo in Lee Hyori's new music video revealing, "I filmed Lee Hyori's music video as a lead role a few days ago. There's no reason for her to not answer my call." Yoo Jae Suk then gave Gil the mission to get Lee Hyori to say, "Oppa, you are so sexy", to Gil over the phone.

Gil then called Lee Hyori and asked her, "When you saw me changing in the dressing room during filming, how did you feel?" Lee Hyori honestly answered, "You were so so." Gil continued to try to get the word "sexy" from her and asked again, "When I was acting like I was in pain, how did you see me?", Hyori was unimpressed and repeated, "It was whatever." Then as a last resort, Gil asked, "If Brad Pitt was acting that part, what would you think?" Lee Hyori replied, "But I don't like Brad Pitt."

Lee Hyori was finally told about the mission and responded, "You're crazy." Yoo Jae Suk then chatted with Lee Hyori and the singer teased, "I don't want to speak for a long time on the phone with you oppa", and hung up the phone to which Yoo Jae Suk shared, "She has a cool personality. Of course, it's Lee Hyori."
