CBS has revealed the identities of the 13 houseguests who will be competing on Big Brother's tenth season, which will premiere Sunday, July 13 at 8PM ET/PT.

"There's somebody for everyone in this cast," Big Brother executive producer Allison Grodner told The Associated Press in a Tuesday report. "It's going to be interesting to see people that come from such opposite worlds living together, which has always been a part of this show, but this season, we really do have our most diverse group ever."

Big Brother 10's cast consists of six females and seven males who range in age from 22- to 75-years-old and hail from Rhode Island to California and various locations in between. They also appear to have a wide spectrum of occupations, from a gay rodeo competitor and a Hooters girl to a Catholic high school teacher and a former Marine. 

In addition, the 13 tenth-season houseguests are all strangers -- representing the first time that has happened since Big Brother's Summer 2002 third season.

"When approaching this season, we wanted to look at what made this spark and last for 10 seasons," Grodner told The AP. "Every season had its unique twist. I think, in a way, going back to basics and having the cast be all strangers is part of the twist of 10. Of course, there will be more."

Grodner played coy about what the additional twist or twists would entail, but reiterated a previous comment that one will play itself out before the debut broadcast.

"It's really a power-play," Grodner told The AP. "The game will actually start before they enter the house."

CBS has also redecorated Big Brother's two-story house to reflect the diverse age range of the tenth-season's cast -- as its rooms will be themed to different decades, such as the kitchen resembling a 1950s-style diner and a bedroom featuring 1970s-inspired furnishings, according to The AP.

Following its July 13 debut, Big Brother will move into its regular thrice-weekly broadcast schedule -- with Tuesday night episodes airing at 9PM ET/PT beginning July 15 and Wednesday night episodes airing at 8PM ET/PT beginning the next night and serving as the tenth-season's live eviction show.  Julie Chen will reprise her hosting role.
