What's New At 'Big Brother 5'?

Thirteen strangers are about to be locked in a house with cameras recording their every move. It can only be an all-new season of "Big Brother."

Reality show host and The Early Show co-anchor Julie Chen tagged along with a couple of previous houseguests to get a peek at the redesigned "Big Brother House." She talked to some of the new contestants who will begin to compete for a half a million dollars.

It's got the feel of a hip hotel. But as former houseguests, Erika and Nathan quickly discovered on their tour that if the new crop of castmates gets too comfortable, they just might end up swimming with the fishes.

"Look it, they have sharks," Erika and Nathan say in unison as they point at a shark tank.

Could this be a not-so-subtle symbol of things to come?

Here are the strategies the new houseguests shared:

Diane, a 22-year-old cocktail waitress from Burlington, Ky., says, "If you step on my toes, I'm going to step right back on your toes."

Jase, a 28-years-old firefighter trainee from Decatur, Ill., shares the same attitude. He says, "If I don't like something about you, I'm going to tell you. If you say something stupid, I'm going to bust all over you."

Scott, 26, is a sales representative from Pittsburgh, Pa. He notes, "I come off real bad, first impressions real bad. I like to wear pink. I'm six-four, a built guy with pink."

The former football player also admits he plans to go topless. Secrets, lies and seduction are always a part of the game.

Karen, 30, is a portrait artist from New Jersey. She says, "Guys are very chemically wired for sexual activity so it doesn't take much to get guys on that level. Ha."

Will, 26, a nurse from Tupelo, Miss., says, "I know how to make people feel attractive and I know how to build people up, so I will rely on some sexual skill to do that, yeah."

Holly, 23, a model from Hollywood, Calif., also shares the same strategy. She says, "I'm definitely a big flirt and stuff. I won biggest flirt in high school."

With lights, mikes, and 42 cameras covering the house, you can run, but you can't hide from 'Big Brother.' Erika and Nathan discover a sneaky addition to the head-of-household room.

They found that in that room you can watch what's going on in other parts of the house. "You get to spy on the house. You can spy on everybody," says Erika.

And another bedroom has undergone an extreme makeover.

Arnold Shapiro, executive producer of the show, says: "The beds are so hard that an Army cot would be considered like a hotel suite bed."

And like every season, he says, there are people in the house who have extreme views from one another.

Personality clashes aside, 13 people sharing a small space with one bathroom will definitely cause sparks to fly.

Drew, 22, and a recent college graduate from Ohio, says, "If we have one bathroom and one mirror, I've been told that I take a while to get ready."

Jennifer, a 21-year-old hostess admits, "I sing weird little songs all the time in little high-pitched voices so that might get on people's nerves too."

Adria, a 30-year-old Web site design from Birmingham, Ala., notes, "I talk about my dogs all the time and that drives people crazy. They're like enough about the dogs."

Holly, a 23-year-old model from Hollywood, Calif., says with a laugh, "If I feel I'm driving people nuts, I'll just tone it down and be more like, what's up?"

Much of the game remains the same. The outside world will watch as the houseguests use their unique talents to try to avoid getting voted out.

Michael, 23, a loss prevention specialist from Oklahoma says, "I'm going to be a good competitor because for one, I'm a sexy cowboy going in the house."

Marvin, a 36-year-old mortician from South Carolina, notes, "I'm an excellent cook. I can cook some stuff and I can hook it up."

Lori, 26, says, "I'm just a flirtatious person and if that gets me further, that's fine." She is a yoga instructor from Boston.

Behind the scenes, they're calling this season of "Big Brother: Project DNA," which stands for "Do Not Assume" anything. However, there's also a hidden meaning, which will be revealed to viewers Tuesday night.

The new twist: Some of the houseguests are related, but they don't know it.

This season "Big Brother" also has a talk show called, "House Calls" premiering Wednesday, July 7, on CBS.com.

By logging on or calling 323-CBS-1000, you, the viewers, now have the opportunity to interact with Marcellas Reynolds, a houseguest on "Big Brother 3" and Gretchen Massey, an on-air host on Infinity Radio's KLSX Los Angeles.

This is your chance to discuss events that transpire in the "Big Brother" house, offer prognostications, analyze strategies, interview former "Big Brother" houseguests as well as current houseguests following their eviction.

The half-hour, streaming video daily talk show is the first produced exclusively for a television network, and it will be broadcast live Monday through Friday (1:00 p.m./ET, 10:00 a.m./PT).

"Big Brother 5" premieres on CBS July 6, at 8:00 p.m., and will be broadcast three times per week on Tuesday (9:00-10:00 p.m., ET/PT), Thursday (8:00-9:00 p.m., live ET/delayed PT) and Saturday (9:00-10:00 p.m., ET/PT).

Immediately following "Big Brother," a new "The Amazing Race" kicks off. Former "Big Brother" houseguest, Alison Irwin, will be among the competitors racing around the globe.
