'Big Brother 15' Houseguests Revealed! Which Player Is Most Likely to Win?

Occupation: Lifeguard. The San Diego resident is entering the house without a strategy. Instead, he hopes to "let my personality flow through the house." Hopefully it flows better than that coif, bra. Most Likely To: Convince a contestant much hotter than him to cut his hair.

Occupation: Professor. The Illinois native looks up to the dreadful Brigade, and also enjoys participating in improv comedy. Which means he's poised to be Big Brother 15's most insufferable cast member. Most Likely To: Be the contestant that has us asking, "Yes, and?" (#ImprovJokes)

Occupation: Property appraiser. The Tennessee native has his time in the house planned out — befriending a strong player, then an older player — but might suffer from being too headstrong. Mostly because his head looks really strong. Most Likely To: Be evicted first.

Occupation: Boat shop associate. Despite that exterior, the Texan considers himself an "alpha male" who will inevitably showmance one of the female contestants on the show. Most Likely To: Realize that Jeremy McGuire didn't have anyone at hello.

Occupation: Youth counselor. The avid church-goer from Mississippi will only miss mass while in the sinful Big Brother. Most Likely To: Reference Judas at least once a week during the season.

Occupation: Entrepreneur. The "X Games-style" skater is excited to see his "full potential" play out on Big Brother. Most Likely To: Take his shirt off and screen "Woo!" upon entering the house.

Occupation: Railroad conductor. The Big Brother superfan's goal going into the show is to be liked. "I'm going to do things to avoid conflict," he says. Most Likely To: Be an annoying floater.

Occupation: College student. The Texan, who has a background in psychology, might be the youngest cast member of the season, but she claims her "life experiences" have molded her into a much more mature person. Which is why she applied to be on a reality show where people wear elf costumes. Most Likely To: Ask for more consonants in her Head of Household room.

Occupation: Unemployed. The Texan has plans to make at least one good friend in the house, or to align with a four- or five-person team. Whatever, she'll figure it out. TV! Most Likely To: Change her occupation to "Actress/Model" following her run on the show.

Occupation: Pageant coordinator. The New Yorker is nice, but doesn't want you to think she's flirting, boys. Now, time to inch that skirt up a little higher. Most Likely To: Break out a pitch-perfect Serena Van Der Woodsen impression.

Occupation: Political consultant. The Chicagoan's seemingly chill nature sets her up for success, but idolizing Big Brother 11 dolt Jeff certainly doesn't spell victory. Or technotronics, for that matter. Most Likely To: Remain unseen and unheard until Week 5.

Occupation: Nutritionist. The North Carolina resident's favorite Big Brother player is Rachel Reilly. Mostly because she's her sister. 'Nuff said. Most Likely To: Lie about Rachel Reilly connection, but give it away when she begins to cry uncontrollably in a fern.

Occupation: Real estate agent. The Long Island native aims to learn and listen to every houseguest before making any allegiance decisions. Most Likely To: Set up an alliance with only the guys, because, for some reason and she doesn't know why, girls just don't like her that much.

Occupation: Bartender. Not quite Minnesota nice, the Midwestern Barnaby plans on being "conniving" and "manipulative" behind her fellow houseguests' backs. She has a good role model — her favorite contestant is Big Brother 11's Matt, who lied about the health of his wife for sympathy. Most Likely To: Quote Fargo.

Occupation: Pizza delivery boy. The house's second Minnesotan calls himself "funny" and "calculating." Most Likely To: Willingly put on a dog costume for our amusement.

Occupation: Pediatric speech therapist. The New Orleans native's plan to lay low and listen is promising, but her germaphobia could be her eventual downfall. Most Likely To: See her toothbrush end up in the toilet. But who cares? She's also most likely to win.
