On September 6th, singer Lee Hyori visited the set of XTM's camping reality program, 'Adrenaline' in support for her close friend, actor Lee Chun Hee.

Hyori and Lee Chun Hee were born in the same year, and have become close through the variety show 'Family Outing'. Lee Chun Hee has been a guest on the show 'Golden 12' for which Hyori was an MC for.

Lee Chun Hee invited Hyori  to the camping grounds without notifying the other members. When Hyori entered the set, all the others greeted Hyori in shock.

Hyori took over the camping grounds with her characteristic charisma and overwhelmed the men. She enjoyed the camping food with the other members, and participated in the game to determine who would do the dishwashing and fully engrossed herself in city camping. She led the mood of the set by exercising her usual friendliness by giving relationship advice to Yoo Ha Joon.

The episode of 'Adrenaline' featuring Lee Hyori will broadcast sometime in mid-October.
