On the September 29th broadcast of KBS‘s ‘Entertainment Relay‘, the actress and her co-star Ji Sung, from the film ‘My P.S Partner‘, were interviewed on the set of the movie poster photoshoot.
The reporter asked the two which idol member they’re interested in, to which Ji Sung brought up [miss A's] Suzy. When asked whether he knows what group she’s in, Ji Sung was hesitant to answer so Kim Ah Joong confidently answered, “Wonder Girls,” causing everyone to laugh.
The actress immediately caught up to her mistake and blushed from embarrassment.
