Brandon C. Showalter was a prospective houseguest on Big Brother 4. Showalter, a 28-year-old computer engineer from Newport Beach, California, was originally announced as part of the show's cast and placed in sequester. However, he would later be disqualified after being caught trying to contact his girlfriend, in violation of the no-outside-communication agreement. He was replaced by Jee Choe.
