First, I need to correct an error. I thought that Cat called Oreo "Snuffalicious," but she sets the record straight in her EW blog: "Snapilicious," though she renders it "Snap-ilious." Need to work on your spelling, Kitten.
Normally, I'd say that the confused blonde (front row, center) is some kind of alien since the uncertain smile and the frantic eyes suggest unfamiliarity with Earth languages and customs...
... but since Oreo was being particularly inane and senseless at the time/always, I can't say for sure in this case.
