2010 Big Brother 12 SPOILERS: Is Ragan Fox The Saboteur?

“For the first time ever, we have someone in the house who, in a way, is playing their own game,” said producer Allison Grodner, who stressed that the operative is not an actor but a real person who was picked alongside everyone else. “They’re playing for a cash prize, if they make it a certain amount of time in the house. If they don’t last, they’re out, and their cover is blown.”

This new exciting new season will debut on Thursday (July 8). The show will give the viewers a week to get familiar with the contestants before the saboteur is revealed on the July 15 episode. You can get uncensored Big Brothers feeds via BB Network with a 33% off discount until July 7 HERE.

Big Brother 12 HouseGuests – Full Cast Bios & Pictures Below

BRENDON VILLEGAS

A high school swim coach from Riverside, Calif., Villegas, 30, will soon pursue a Ph.D. in biomedical physics. Though he describes himself as “very much a nerd,” he’s really a combination of brains, brawn and brown-eyed good looks. “My goal is to not intimidate the guys and to be flirty with the girls,” says Villegas, who may be up for a showmance. “The girl that is down-to-earth and sweet is going to be the biggest challenge for me.”

RACHEL REILLY

A graduate student in chemistry and VIP cocktail waitress from Las Vegas, Reilly, 26, has a secret weapon — or two. “Most people look at me and think that I’m just a hot girl with big boobs,” she says. “I can manipulate men and the bikinis that I brought are not even the size of my palm. They’re super tiny! I’m going to hustle them with my Vegas-cocktail personality.”

KATHY HILLIS

A deputy sheriff-sergeant from Texarkana, Ark., Hillis, 40, is the only contestant who has (legally) ordered someone to “cough and drop.” But this single mom, who has survived cancer, has a simpler motto: “Never give up, never give in and never use the word defeat,” she says. “When my grandma was terminally ill, we would watch BB together and … I promised her that I would [try out for the show] when we both got better. And though I got better, she didn’t [so] I’m going win it for Grandma!”

ENZO PALUMBO

An insurance adjuster from Bayonne, N.J., Palumbo, 32, is happy to wear a stereotype on his sleeve and “shore” up that Jersey “situation.” His message to fans: “When I get into that house, competition is going to be served like my mother’s baked ziti,” he says. “That is how I am going to be playing this game.”

ANNIE WHITTINGTON

A bartender from Tampa, Fla., Whittington, 27, says she may keep her bisexuality a secret. “There may be some more close-minded people in the house and I don’t want to be judged,” she says. “There are so many more facets to my character … I don’t think who I sleep with should be that important to anybody.”

MATT HOFFMAN

A Web designer from Elgin, Ill., Hoffman, 32, is quick to list his strengths — “My tattoos, coming into BB, are my greatest asset,” he says, “along with being a genius.” — as well as a weakness. “One of my worst character traits is the fact that I can be really condescending,” he reveals. “It’s something that I’ve tried to work on but everyone aggravates me.”

KRISTEN BITTING

A 24 year-old boutique manager from Philadelphia, Pennsylvania. “I am a quiet storm,” says Kristen. “I don’t think there is anyone on reality TV quite like me.” Her motto is “Grab life by the balls!” This girl is TROUBLE!

HAYDEN MOSS

A 24 year-old college student from Tempe, Arizona. “Athletically, I’m pretty gifted, so the physical competitions are going to be in the bag,” says Hayden. “Also, I’m smarter than I look.” The nice guy!

BRITNEY HAYNES

A 22 year-old hotel sales manager from Huntington, Arizona. “I’ll pretend to be nice and always a bit elusive,” says Britney. “People want what they can’t have and I’ll give them just enough.”

ANDREW GORDON

A 39 year-old podiatrist from Miami Beach, Florida. “Live for today because tomorrow will be yesterday soon,” says Andrew. “Say anything, do anything, just don’t let them know and trust no one.” Andrew is an Orthodox Jewish, which may prevent him from competing on Saturdays and he is also Kosher.

RAGAN FOX

A 34 year-old assistant professor from West Hollywood, California, who is also a poet and has his own radio show. “I party as hard as I work, and I grew up gay in Texas,” says the college professor from West Hollywood, Calif. “If you want to get crazy with me — and I opt to go crazy — then you’re in trouble.”

MONET STUNSON

A 24 year-old aspiring model from Glen Carbon, Illinois. Monet is annoying and totally self-absorbed. “I come off as really sweet and innocent,” she says. “People won’t expect that I would lie to their face and stab them in the back to win.”

LANE ELENBURG

A 24 year-old oil rig salesman from Decatur, Califrornia. Lane is very competitive but he also considers himself a nice guy and makes friends easily. “I’m a big guy, so I know that I have to find a smart guy,” says the oil rig salesman. “I have to find a ‘brain’ for the ‘meat head.’ ”
