Expect the unexpected -- including sisters on Big Brother: Over the Top.
CBS revealed the 12 new cast members Monday, which include a pair of sisters -- Alex and Morgan -- a debt collector, a seafood restaurant owner and someone nicknamed Cornbread. They range in age from 21 to 41, and a majority of them are Southern. Click here to learn more about the new houseguests.
The newbies will join one of two alums who will re-enter the house, as voted on by CBS All Access subscribers: Season 17's Jason or Season 18's
Messiah Jozea. Voting is open until 3 p.m. ET / 12 p.m. PT on Tuesday.
As previously announced, fans will have more impact on the game than ever before on Over the Top, including voting for the winner, as there won't be a jury. There will also be daily episodes at 10 p.m. ET / 7 p.m. PT, as detailed here. In addition, beginning Oct. 4, fans can watch live diary room sessions on Tuesdays and Fridays at 10:30 p.m. ET / 7:30 p.m. PT.
Here's how Big Brother: Over the Top will work
"We're not revealing all the details as to what else the public will control, but they will control other elements of this game," host Julie Chen tells TVGuide.com. "I think people who are already All Access subscribers, they will love it. People who only like to watch the three episodes a week on the broadcast version because they like to watch what the network wants you to see or deems important, they will probably have some getting used to. But I'm telling you, I tuned in the other day to watch Nicole sleeping and there was nothing going on and I was interested."
Chen is also curious to see which of Jason and Jozea fans will vote back in. "I think it will be close between them," she says. "Jason is a superfan, but Jozea is good TV."
The Messiah, for his part, says you will see a different Jozea if he's lucky to return. "I honestly want to show people Jozea, not the Messiah," he says. "We all met the Messiah. I want to show them the real me, who I am. I actually watched the game this time. I studied the game, I learned the game, and I feel like I can actually play Big Brother and win the game."

And what are the chances that both end up returning? Pretty good. But Jason has no interest in sharing the house with Jozea. "I sure as hell don't want to live with him," he says. "After watching him for one week, that was enough for me. I'm a real feed-watcher, so I've seen what feels like more than a week's worth of Jozea. I've seen basically all of his body except about a square inch. The voyeurs -- go ahead and vote for him because he's going to walk around in his underwear. But the real Big Brother fans, I hope they see I'm here to play strategy and I'm not here to scoop up Instagram followers or become a model or get signed or anything like that. I don't want to get into showbiz, I just want a fat check."
