THE "BIG BROTHER: ALL-STARS" HOUSEGUESTS SEND BAD GIRL ALISON PACKING!

Alison Irwin Is the First Houseguest to Officially Be Evicted From the BIG BROTHER: ALL-STARS House

After being nominated for eviction by Janelle Pierzina and Jase Wirey, the first ever co-Heads of Household, Alison Irwin was evicted last night from the BIG BROTHER: ALL-STARS House by a vote of 8-2 by her fellow Houseguests, with everyone voting out Alison except Diane and Nakomis (Heads of Household and the two eviction nominees do not vote). On Tuesday, Janelle pulled a double whammy by also winning the Power of Veto, but chose to leave the nominations as they stood, leaving Alison Irwin and Danielle Reyes on the chopping block.

During last night's live broadcast, the 25-year-old Medical Sales Representative originally from Meadville, Penn., who currently resides in Columbus, Ohio, learned her fate and left the House. After leaving BIG BROTHER: ALL-STARS, Alison was interviewed by Julie Chen about her experience.

The Houseguests compete each Thursday to become Head of Household. The perks of the position include having a luxurious private bedroom and bathroom, as well as a plasma screen spy cam to monitor other Houseguests' activities. However, it also includes the responsibility of having to nominate two fellow Housemates for eviction. On the weeks when there are veto challenges, one of the nominees can be saved from the chopping block if they or another Housemate wins the Power of Veto competition and chooses to save one of the nominees, while giving themselves immunity from nomination. If they choose to use the veto power, the Head of Household must immediately choose another nominee.

After last night's eviction, the houseguests competed in a competition called "Alison's Rules" to see who would become the next Head of Household. Kaysar Ridha, the 25-year-old graphic designer from Irvine, Calif., won the coveted position.

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.
