'Big Brother': Unanimous Vote Sends First Female Of The Summer Packing (VIDEO)

Week after week, some of the strongest guys in the game this season have been evicted from the "Big Brother" house. This week, for the first time it was assured that a woman would be going home. After taking herself off of the block earlier this week, the replacement nominee for Elissa was GinaMarie. She joined Aaryn and Kaitlin, who'd been put on the block by Head of Household Judd.

Aaryn did some effective last-minute scrambling, promising her loyalty to Helen and her crew, and even promising them the power to pick the nominees if she won HOH this week. When it came time to vote, Aaryn's promises seemed to have saved her. Despite Elissa wanting her out for personal reasons, it was a unanimous decision to eliminate Kaitlin.

Kaitlin was one of the house's "mean girls," which came as a shock to her when she got out of the house. Julie Chen asked her why she participated in such ugly behavior with the other two, Aaryn and GinaMarie -- like flipping Candice's mattress.

“I think it definitely rubbed off on me. It showed some characteristics that aren’t necessarily mine, and it happened," Kaitlin said. "I definitely picked the wrong side of the house, but what can you do?” It was an assessment that Reality Rewind's Todd Betzold agreed with. He wrote that "she was the nicest of the mean girls and just got caught up in the wrong group."

Darren Franich of Entertainment Weekly was a little surprised by her eviction. "Kaitlin had played a relatively quiet game, and seemed like the lesser of three evils," he wrote. "But Aaryn made a significant case for herself ... Kaitlin was a serious competitor.”

Setting up an interesting week, Aaryn did become the new HOH. Will she keep her word to Helen and that alliance, or will she go rogue and start targeting the people she's been wanting out since the beginning -- in other words, Elissa!

Find out how it plays out as "Big Brother" continues on Sundays and Wednesdays at 8 p.m. ET, and Thursdays at 9 p.m. ET on CBS.
