T-ara's Eunjung exhibited her cute and refreshing charms in a recent photoshoot for 'Singles'. The photoshoot revolved around the 'naughty girl' concept, and the idol was decked in vivid, brightly-colored clothes. She posed confidently, giving off the vibe of a spoiled 'naughty girl'. When the concept was first explained to the singer, she expressed her concerns over its difficulty, "It doesn't work well if you force yourself to do it." But when the lights came on, Eunjung posed like a professional. Because Eunjung is extremely busy with her "Dream High" filming, the photoshoot started at 6:00 AM.  Without showing any signs of fatigue, the idol got right to work. She also tweeted on February 18th, "So I hear that the concept for Single's March edition photoshoot is 'naughty girl'? Haha... A few pictures were already revealed, so I'm posting pictures that I had on my phone. Blonde... and red lips. Whoa whoa. My heart is pounding".
