Although Stellar stopped promoting "Vibrato" a while ago, they've decided to treat fans to more behind-the-scenes cuts as they wait for news of a comeback.

While the cameras are rolling, each member gives 100% to the seductive theme of the MV. However in between takes, the girls play with the camera, shower fans with hand hearts and winks, and behave rather cutely. It's great to see the fun and sexy side to the Stellar members.
