In a new clip on MTV.com, Katy and her sister, Angela Hudson, have some fun at a waterpark on their day off.

"We always kind of had this deal that when she made it big, that I was going to work with her and we were going to be together," Angela says in the clip.

Does anyone have a deal like that with any of their friends or family members? Make them stick to it! If Katy's success is any indication, dreams do come true!

Angela continues on to say that Katy "plays hard" just as she "works hard" and it looks like sometimes, Angela finds herself adapting to Katy's idea of fun, which might not really match up with hers. The two hit a waterpark, and drop from towering heights in one of the rides (Angela's afraid of heights, by the way). We're not at all surprised that Katy thinks people should do things that scare them!
