J.Y. Park had the spotlight all to himself on the April 13 airing of 'Cultwo,' chitchatting and joking around with the DJ's to his heart's content. 

When the DJ's asked him, "You hold your end-of-the-year 'Bad Party' every year, right? Just how bad is it that you call it 'Bad Party'?" J.Y. Park answered, "It's really bad. Minors aren't allowed to attend. There is a greater number of females at the concert. It's around 8 females to every 2 males."

J.Y. Park also revealed, "Every time I promote, I shed around 2 to 3 kilos (4.4~6.6 lbs)," and added, "The image of you dancing and singing is a fantasy. So your arms have to look long," emphasizing the need to upkeep your physical appearance when you're a big star like he is.
