Popu Lady released Gossip Girl yesterday, and it may be their last song as a five-member group. I'm sure after seeing how well f(x) has been received as a four-member group, maybe Popu Lady thinks they can kick out their own Sulli.
The song is alright. It deviates from the saccharine sound they are known for, but their pre-release tracks were better, especially this song. At the very least, they all look really hot in the MV.
