On the July 29 airing of KBS 2TV's 'Happy Together 3,' HyunA appeared and talked about what she sleeps in.

She said, "I think that your pajamas are important.  What you wear depends on your mood. On days I want to be a late-teens star, I wear a two-piece lingerie and slip to bed," making it hard for Junhyung to hold back a snicker.  

She asked the other MCs if that was weird and they replied, "No.  [He's laughing] because it's funny.  It's funny that you're alone but you [dress] like that."

Still unable to get over Junhyung's reaction, she said, "I'm not a weird person who does that every day.  There are times I dress comfortably to bed, too.  There are times I even wear just long pants."

Lee Soo Min showed her understanding, stating, "I also like pretty pajamas. That's why I have a lot of one-pieces at home.  But when I wear those to sleep, the skirt rides up."
