On a primetime special last night, CBS announced the 20 potential houseguests who will campaign to compete this summer in BIG BROTHER: ALL-STARS, the seventh installment of the reality series.

Viewers can now vote which former Houseguests should compete this season with the television audiences choosing half of the houseguests who will ultimately enter the BIG BROTHER house. Viewers can cast their votes online at CBS.com. The polls will close on Wednesday, June 28 at 11:59 PM, ET/8:59 PM, PT.

Each potential "All Star" introduced on the casting episode last night has their own profile on CBS.com, which includes "Why you should vote for me" text and video, as well as clips from their past appearances on BIG BROTHER.

Additionally, throughout the voting process, candidates will be able to campaign for themselves and state their case to America as to why they should be voted into the BIG BROTHER: ALL-STARS house.

During the premiere of BIG BROTHER: ALL-STARS, all 20 candidates will be present and awaiting the news of who will play the game. Host Julie Chen will announce the 12 who will immediately enter the house.

BIG BROTHER: ALL-STARS will follow 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 premieres Thursday, July 6 (8:00-9:00 PM, ET/PT) on the CBS Television Network. Following the premiere, BIG BROTHER: ALL-STARS will be 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.

BIG BROTHER: ALL-STARS AMERICA'S VOTE will be rebroadcast on Saturday, June 24 at 8:00 PM.
