Continuity mistake: When the six girls arrive for the party, in the first shot Tom-Tom tosses her blue jacket, then the second girl lays her red jacket and the third girl starts to put her pink jacket into Jenna's arms. Yet, at the start of the next shot facing Jenna, she holds only the blue jacket, since the red jacket is gone, the pink jacket is placed in Jenna's arms on top of the blue jacket and then the red jacket is thrown into her arms from off camera, before the rest of the girls dump their jackets into her arms. Then in Jenna's close-up, the jackets are positioned very differently in her arms. (00:08:15)
