10. Girl Power / Elite Eight
In one of the biggest twists in Big Brother history, season 4 featured Houseguests that would be living with their exes. The original Houseguests were informed of the news and decided to create the Elite Eight alliance to combat the incoming exes. After a series of betrayals, The Elite Eight collapsed, until Alison Irwin, Erika Landin and Jun Song resurrected the team and renamed the alliance Girl Power. Girl Power finished the job that the Elite Eight started by evicting the exes. Alison and Jun eventually made the final two, with the latter winning the grand prize.
