"BIG BROTHER: ALL-STARS" TREATED TO A BLAST FROM THE PAST

Former Big Brother Houseguests will Return to Participate in this Week's Head of Household Competition, Food Competition and Veto Competition

Julie Chen Will Announce Details for this Season's Newest Twist, the "Coup d'Etat" on Thursday, Aug. 10

The remaining Houseguests competing on this season of BIG BROTHER: ALL-STARS will be treated to some familiar faces this week as several former Houseguests lend their services to this week's Head of Household competition on Thursday, Aug. 10, the Food Competition on Sunday, Aug. 13 and the Veto Competition on Tuesday, Aug. 15.

The first group of former BIG BROTHER Houseguests will return for a surprise cameo appearance this Thursday, Aug. 10 (8:00-9:00 PM, ET/PT) during the live eviction show. The former Houseguests will be incorporated into the HOH competition, which will require this season's All Stars to recall specific clues they have received from the former Houseguests throughout the week in order to be crowned this week's HOH. Another group of former Houseguests will return to serve as judges during this week's Food Competition on Sunday, Aug. 13 (8:00-9:00 PM, ET/PT). The BIG BROTHER blast from the past week will conclude with former Houseguests also playing a role in the all important Veto Competition on Tuesday, Aug. 15 (8:00-9:00 PM, ET/PT).

During the Live broadcast on Thursday, Aug. 10 (8:00-9:00 PM, ET/PT), host Julie Chen will explain this season's newest twist, the "Coup d'Etat," which she teased at the end of last week's live eviction show. The "Coup d'Etat" will enable one person to overthrow the HOH at a moment's notice.

BIG BROTHER: ALL-STARS follows the relationships and conflicts of players who live together in a house outfitted with dozens of cameras and microphones recording their every move 24 hours a day. One by one, the houseguests will vote each other out of the house. At the end of three months, the last remaining houseguest will receive the grand prize of $500,000. While living together in a confined space won't be anything new to the Houseguests, choosing between any pre-existing relationships and building new alliances could be a challenge.

BIG BROTHER: ALL-STARS is broadcast each week on Tuesdays (8:00-9:00 PM, ET/PT), Thursdays (8:00-9:00 PM, live ET/delayed PT) and Sundays (8:00-9:00 PM, ET/PT). The Thursday broadcast, hosted by Julie Chen, will feature the live eviction of one of the houseguests.
