There is no question that Girl's Day exceeded everyone's expectations with their explosive track, "Nothing Lasts Forever," last year -- the only question that remains is, can the ladies repeat their success again? With a comeback scheduled for this month and a MV teaser released earlier today, DreamTea Entertainment has released to allkpop a set of album concept photos, giving fans their first glimpse at what this return will look like. And we're definitely liking what we see! Girl's Day has confirmed that their new track is titled "Twinkle Twinkle (????)." With their youthful & vibrant outfits, it seems like the quintet has abandoned the previous leather look and is going for an energetic & preppy concept this time around.  A representative from DreamTea Entertainment expressed, "We're going to use the colors of their hair and accessories to really show a bright and fresh image for their concept."

Make sure to stick with allkpop as DreamTea Entertainment is scheduled to release their full music video soon!
