Haleigh Broucher and Faysal Shafaat could not vote since Haleigh was the week's Head of Household and Faysal's vote was taken away from him due to the "BB Hacker" twist.
"I said I wasn't going to allow myself to be blindsided, Julie, but I must admit, I was not expecting that. I think that little trio did their work and talked a better game or something," Rockstar told Big Brother host Julie Chen in her post-eviction eviction.
Rockstar thought Sam was the one houseguest who had voted for her to stay, but she was wrong. She felt the most betrayed by "whoever came up with that hacker twist," and said she continued to be a target because she was "fierce." Rockstar also reiterated how Angela Rummans is an "entitled, spoiled brat."
The Big Brother broadcast began on Day 55, with Kaycee back on the chopping block. But Kaycee knew "Level 6" had her back, and Tyler Crispen agreed she wasn't going anywhere.
Meanwhile, Rockstar -- who was on the block for the third time -- had no intention of giving up, as she's a self-proclaimed "badass b-tch." She thought she had Faysal, Sam Bledsoe and Scottie on her side, while JC Mounduix also votes with the majority vote.
Haleigh hoped the house would take this chance to take a competitive athlete out of the house who's actually playing the game.
Rockstar then apologized to Kaycee for her position, as Angela had been her alliance's real target this week. Kaycee was shocked Rockstar was so confident and assumed she was safe, because Kaycee predicted the vote was going to be 5-1 in her favor.
Kaycee also squealed to Angela that Rockstar had called her "entitled." Rockstar complained Angela always gets what she wants.
Tyler was then shown reassuring Sam that they were still ride or dies, as they had promised each other a Final 2 deal on Day 1.
Faysal said he cared more about Haleigh than he did about the game, and then he swore to ride with her "until the wheels fall off."
After 54 days in the house together, Faysal and Haleigh finally shared a kiss, and she couldn't believe she did it since her father was watching.
At the beginning of the game, Rockstar and Brett Robinson were at each other's throats, so in an unexpected twist, the pair decided to team up and work together because no one in the house would ever suspect they had a "secret alliance."
But Brett had no intention of staying true to Rockstar, who named their alliance "Mr. and Mrs. Smith."
"I'm going to build up all of her hopes and dreams and take them away from her. Rockstar, we certainly have that Brangelina charm, and like other Hollywood marriages, this is going to end in divorce," Brett said in a confessional.
Brett shared with Angela, Kaycee and Tyler about his so-called pact with Rockstar, and everyone laughed at the idea.
Brett was playing both sides of the house pretty hard -- he even helped Rockstar come up with her speech to deliver before the next live eviction. Rockstar was planning to expose a Final 2 alliance between Tyler and Angela in her speech, warning Kaycee that she was just empowering a duo in the house.
When it became time for the live eviction, Kaycee threw Rockstar under the bus for plotting to form an all-female alliance with the exception of Sam.
But then Rockstar addressed the group saying anyone who votes with Tyler, Angela and Kaycee is just empowering a strong, unbreakable threesome, who will pick everyone else off one by one.
The "BB Hacker" -- who was secretly Kaycee -- then announced he or she had chosen to prevent Faysal from casting his vote.
After Rockstar left the house with five votes, it became time for the season's next Head of Household competition.
As the outgoing HoH, Haleigh was deemed ineligible to compete.
The competition, dubbed "Glow & Flow," required the participating houseguests to retrieve fuel, slide across a soaped-up dance floor, and fill a glow stick on the other end. If a houseguest chose to fill up a small glow stick instead, that person would win $5,000.
The first person to fill up the larger glow stick would become the new Head of Household.
