Big Brother 11 premieres on CBS this Thursday, July 9, 2009, at 8 pm/ET. This season is being advertised as "bigger secrets", "better than ever", "crazy new challenges", and "outrageous summer fun" according to the new promotions. This season of Big Brother will pit 12 houseguests against one another, in another seasonal battle to decide who is going to go home with the cash prize. Julie Chen will host the show again and one of the first surprises will be who is the mystery 13th house guest.
The show has also announced this season's new "green" house.
