During TWICE's guest appearance on this week's 'Weekly Idol', MC Jung Hyung Don asked about her drastic haircut and stated, "There's always a reason when a girl cuts her long hair."

Chaeyoung answered, "I just wanted to cut it." Jung Hyung Don continued to be suspicious, and Chaeyoung responded, "I'm the type who has to do it when I get into something. I saw that Kristen Stewart cut her hair short and I liked it so I got it cut."
