Intro/How Big Brother works

Dasia McKnight and her best friend, Wynn Harold, are Big Brother's biggest fans. So when they apply to be on the show, and they are accepted, they would expect a summer full of competition and drama. But what about love?

So this story is based off on CBS's Big Brother (USA) which airs during the summer. I have been watching it for a few years now and thought about a summer that has all of our favorite celebrities. I believe that this is half au, half not, since all of the characters have very similar traits to them in real life.
Before anyone asks, I do have the story line roughly thought out (evictions, and the winner of course). But I am open to any NOT game changing drama ideas. :)
