G.NA joins SECRET in place of Zinger?

Singer G.NA took a cute selca with girl group SECRET and tweeted the adorable photos. On June 26th, G.NA tweeted along with the photos, "Everyone worked really hard today. Wheesung oppa was, of course, the best. It's been awhile since I've seen SECRET, and it was for a short time. It's always nice to see them. It's SECRET time". In the photo, G.NA is posing with members Ji Eun, Sunhwa, and Hyosung. Rapper Zinger is missing from the picture, which made G.NA seem like the fourth member. The girls had met up backstage at the "Inkigayo" Summer Special this past Sunday. Netizens wrote, "SECRET's fifth member, G.NA", "All four are doing their own thing", and�"Where is Zinger?"
