CBS' popular reality show "Big Brother" is back for its 13th season and viewers can expect an all-new cast as well as a few other oldies but goodies.The eccentric housemates seem ready to give it a go in this new season to vie for the $500,000 grand prize. Houseguest Cassi sums it up perfectly when she says, "I’m pretty black and white, but then again, it's a game." It is a game indeed, one with an interesting new twist that they call "double trouble," and we can bet there will be more than a few isolated incidents. (ETonline.com)
