Entertainment said that "Tisdale wants to dance, and not in that G-rated, Disney-fied way, either, in this video. We see her practicing some sexy moves, seductive looks and various hand-to-hair gestures after watching. Fortunately, all that preparation eventually pays off, and she finally makes it onto the dance floor".
