Brown Eyed Girls’ Ga In appears in PSY’s “Gentleman” video. She spoke about it with OSEN through a phone interview on April 15. She stated, “One week before filming, I received the offer to appear in the music video. I was more nervous when I prepared my own album. I had to wear clothes that revealed a lot of skin, and one week was too short of a time for a proper diet. I ended up eating only one meal a day. More than having a good effect, I chose the diet to console myself.”
