Big Brother 4 debuts tonight; one house guest already replaced by an ex.
On the eve of its debut, a Big Brother 4 house guest was removed from the program, and will be replaced by another house guest’s ex—bringing the total number of exes who will eventually join the program to five. Brandon Showalter, a California-based computer engineer, was pulled because producers “were concerned about how he would handle up to three months with no contact with the outside world,” Zap2it.com reports. Additionally, a spokesperson “confirmed reports that Showalter may have tried to contact someone during the time he was sequestered before entering the house.” The show debuts on CBS tonight at 8 p.m. ET, and will air Tuesdays and Fridays at 8, and Wednesdays at 9.
