Entertainment Round-Up: Evel Dick Tweets, Fight Over Farrah, Celebs Thank Betty Ford

LOS ANGELES (CBS) — Evel Dick Donato left the "Big Brother" house Thursday reportedly to attend to a "personal matter." The show said his reasons for leaving would be addressed on the program airing next Wednesday.

In the meantime, Donato tweeted rather cryptically Saturday: "Some things in life are more important than a tv show. Those things give you perspective in your life. This is one of those things"
