Less than a month after a CBS.com glitch prematurely revealed the identities of the twenty former houseguests that viewers would be able to vote into this summer's Big Brother 7: All-Stars house, another online glitch has apparently prematurely revealed the identities of the season's cast.

SPOILER ALERT: This story contains Big Brother 7: All-Stars spoilers -- please stop reading immediately if you aren't interested in knowing these spoilers

Although they aren't scheduled to go live until after Thursday night's season premiere, Big Brother 7: All-Stars' live feeds briefly began streaming live audio on Tuesday afternoon. In addition to revealing that, despite previous reports that neither the public nor the finalists themselves would learn which former houseguests would be part of Big Brother 7: All-Stars until the show's "live" premiere, the houseguests (as they normally do each season) have already entered the Big Brother house, the unexpected audio feed also allowed live feed listeners to not only identify this season's cast, but also discover two of competition's apparent twists.

According to JAM! Showbiz, while the feeds were only live for about an hour, that was long enough for listeners to hear Alison Irwin (Big Brother 4 first runner-up), Danielle Reyes (Big Brother 3 first runner-up), Diane Henry (Big Brother 5 second runner-up), Erika Landin (Big Brother 4 third runner-up), George "Chicken" Boswell (Big Brother 1 fourth runner-up), Howie Gordon (Big Brother 6 fourth runner-up), James Rhine (Big Brother 6), Janelle Pierzina (Big Brother 6 second runner-up), Jase Wirey (Big Brother 5), Jennifer "Nakomis" Dedmon (Big Brother 5 third runner-up), Kaysar Ridha (Big Brother 6), Marcellas Reynolds (Big Brother 3 fourth runner-up), Mike "Boogie" Malin (Big Brother 2), and Will Kirby (Big Brother 2 grand prize winner) speaking on the live feeds.

Based on their absence from the live feeds, remaining Big Brother 7: All-Stars finalists Bill "Bunky" Miller (Big Brother 2 fourth runner-up), Dana Varela (Big Brother 4), Ivette Corredero (Big Brother 6 first runner-up), Lisa Donahue (Big Brother 3 grand prize winner), Michael "Cowboy" Ellis (Big Brother 5 first runner-up), and Monica Bailey (Big Brother 2 second runner-up) are not believed to be currently living in the Big Brother house.

Since fourteen houseguests were heard speaking on the live feeds, it appears that Big Brother 7: All-Stars' first twist is that despite CBS's multiple announcements that the All-Stars edition would only feature twelve houseguests, the season will instead -- as Big Brother executive producer Allison Grodner hinted at back in April -- somehow begin with fourteen houseguests living in the house.

Assuming the fourteen houseguests heard on the live feeds represent this season's full cast, then in addition to drawing exactly half of its cast from the long-running reality show's most recent Big Brother 5 and Big Brother 6 editions, Big Brother 7: All-Stars will also feature a gender-unbalanced cast comprised of eight men and six women. Big Brother 7: All-Stars' pool of twenty finalists had been equally comprised of ten men and ten women. Last summer's Big Brother 6 cast featured eight women and six men.

Additionally, live feed listeners also discovered that the show's first Head of Household competition (already conducted by the time the feeds began streaming) had crowned not one by two houseguests -- Jase and Janelle -- as Big Brother 7: All-Stars' first Head Of Household. According to the live feed discussions, Jase and Janelle must jointly agree on which two houseguests will be nominated for the game's first eviction. Should Jase and Janelle fail to agree on which to houseguests should be nominated, they themselves will be nominated for eviction. Left unclear was whether the dual HoH twist will be a one-time event or a permanent part of this season's gameplay.
