1LLIONAIRE's Dok2 was one of the guests on the July 13 airing of 'Radio Star.' 

The rapper's guest appearance was an aberration of sorts because he has stated in the past that he "doesn't do variety." When the MCs pointed out that 'Radio Star' is a variety show, Dok2 disagreed, reasoning, "'Radio Star' is a talk show and 'I Live Alone' is a reality program. To me, a variety program is one where you complete missions and run around."

Dok2 also denied being a celebrity, instead declaring himself a "rap star." Kim Gu Ra, upon hearing Dok2's statement, wisecracked, "Then is Kim Bo Sung a 'movie star'? That means none of us here is a celebrity," making the studio ripple with laughter.
