She was asked if she ever rebelled before. She answered, "Hmm which one should I say? They're all really strong. It was when I was filming a teaser for the title track 'Because I'm The Best' from my 4th mini album." She continued, "The CEO of the company wanted me to do music that showed my cocky side because I'm a little sensitive. So I thought to myself that I should definitely try to deviate away from my sensitive personality. To film the teaser, I went out with foreign friends in Los Angeles to just drink, party, etc., and I went topless." To this information, the cast of the show was shocked.
