Pledis Entertainment revealed today the new 6th member for their girl group After School through their new song teaser, Diva. The new member is Kim Yoo Jin, who is otherwise known to be one of Wonder Girl Yoo Bin's best friends from highschool. They also appeared together on MBC Introducing Star's Friend last year where Yoo Bin introduced her to the delight of the guys who were mesmerized by her good looks and S-line figure. This will be Yoo Jin's second attempt at a singing career, as she was in training as Good Entertainment’s Five Girls group together with Yoo Bin before they got disbanded due to financial issues. In the teaser clip which looks to be another win-win catchy tune with the chorus going "diva, diva di-di-di, diva", Yoo Jin is picked up from the streets by the 5 existing After School members on a random drive. The nerdy looking Yoo Jin is then given a wardrobe makeover by them and she becomes a diva just like them I suppose. credit: AfterSchoolCraze Filming for the music video took place over the past weekend, and the full version will be released very shortly. After School, who took a short break after concluding their 1st mini-album promotions on 22nd March, will be making their comeback this Thursday, 9th April via Mnet M! Countdown. Their new single Diva will also be out on the same day. We all knew what happened when Kim Yoo Bin joined the Wonder Girls in 2007, but will Kim Yoo Jin yield the same effect with After School two years later? thanks to Xee, mia and N for tip.
