Big Brother Season 13 picture of the graffiti-themed backyard

CBS must have gotten a great deal on florescent spray paint because the back yard of the Big Brother Season 13 house is decked out in some serious graffiti! This preview photo shows the backdrop in front of which a lot of the drama will play out on this season of Big Brother set to premiere July 7. (Click photo for a larger image) The house seems to have a beach amusement park theme – You can CLICK HERE to see tons more photos of the interior and exterior of the Big Brother 13 house and for the first batch of photos released of just the interior of the house.
