In a new clip from Katy Perry's upcoming film, we see how close she is to her older sister, Angela Hudson. Yahoo! posted the preview clip for "Katy Perry: Part of Me," in which Hudson says, "We always kind of had this deal that when she made it big, I was going to work with her and we were going to be together." We see Katy and Angela hang out at a water park and the two take a plunge on a bungee-type apparatus - a big deal for Hudson, since she's afraid of heights.
