'Big Brother 18' Cast News: Will Bronte & Bridgette Keep Up Their Positive Personalities? [POLL, VIDEO]

Bronte D'Acquisto and Bridgette Dunning are two new Big Brother houseguests who might use their sunny personalities to excel in the game.

Earlier in the week, CBS announced the 12 new houseguests entering the Big Brother house this year. Two of those new houseguests are Bronte and Bridgette, and for those who have seen their interviews with CBS/Jeff Schroeder, both seem to have a very positive outlook on life.

Bronte, 26, is a student from Denver, Colo. who is hoping to play similar to Big Brother 16 winner Derrick Levasseur.

"Before I make a move, I am going to think through the worst-case scenario of what might happen with my decisions, and then come up with solutions for them!" she says in her CBS bio. "Houseguests tend to focus on how everything will play out perfectly and then they don't know how to get out of a sticky situation."

As for Bridgette, a 24-year-old traveling nurse from Ventura, Calif., she wants to downplay her own strengths in order to make it far into the game.

"People tend to underestimate me. I look very young, I can be a bit gullible and oblivious at times, and I tend to be goofy and playful," she says in her bio. "I plan to let them think what they will and let them disregard me as a threat. What they will not expect is for me to be extremely smart. I can-and will-outwit others with my gameplay and strategy."

She continues, "Once it's down to the Top 10 or so, I should definitely be on a team or alliance, which will hopefully include someone who is physically strong and someone who is easy to manipulate. I plan to keep secrets and promises, but I also plan to spread small bits of doubt and leak rumors. I want to be behind the scenes, manipulating someone else in the house to look like a bigger threat than me each week until the finals, where I will blow them all away and get into the Final 2."
