Ronnie Talbott became the fourth houseguest evicted from Big Brother's eleventh season during Thursday night's live broadcast of the CBS reality show.

Ronnie, a 30-year-old gamer from Belpre, OH, was evicted from the Big Brother house via a 4-3 vote on Day 33 after he was placed on the chopping block by the competition's fourth Head of Household Russell Kairouz, a 24-year-old mixed martial arts fighter from Walnut Creek, CA.

Russell had nominated Ronnie for eviction alongside Lydia Tavera, a 24-year-old special effects make-up artist from Torrance, CA.  Michele Noonan, a 27-year-old neuroscientist from Pasadena, CA, won the week's subsequent Power of Veto competition but declined to remove either nominee from the chopping block, leaving Russell's nominations unchanged.

Lydia ended up receiving evictions votes from Jessie Godderz, Natalie Martinez and Chima Simone -- Ronnie's three house allies -- while Ronnie received votes from Michele, Kevin Campbell, Jeff Schroeder, and Jordan Lloyd.

Prior to Ronnie's eviction, the broadcast also revealed that home viewers had voted to award Jeff the secret "Coup D'etat" mystery power Big Brother host Julie Chen had announced last week. 

The power -- which Jeff can not disclose to any of the other houseguests and was also featured but never actually used in Big Brother 7: All-Stars in 2006 -- granted him a one-time right to overthrow a Head of Household's nominations and replace one or both of the nominees immediately before one of the house's next two live eviction votes.  Jeff opted not to utilize the power before Ronnie's eviction vote, leaving him with the option to use it prior to next week's eviction vote.

Following Ronnie's eviction, the nine remaining houseguests -- minus Russell, who as the outgoing HoH, was deemed ineligible to compete -- competed in the season's fifth HoH competition.

Dubbed "Say What," the true/false competition required the Big Brother houseguests to correctly remember the details of home viewer audio messages they were forced to listen to on Wednesday night.  Every houseguest was required to display an answer to each question, with correct answers allowing them to remain in the competition and incorrect answers resulting in their eliminations.

Michele and Lydia were the first two houseguests eliminated from the competition and Jessie followed two questions later. Jeff and Jordan then both missed the fourth question, leaving only Chima, Kevin and Natalie in the competition.

Chima was the only one of three remaining houseguests to answer the next question correctly, resulting in her becoming the season's fifth HoH.

Big Brother 11's next episode will air Sunday, August 9 at 8PM ET/PT on CBS.
