Big Brother returns

Feb 12, 2008 at 3:01 p.m. ET

It's the first ever all-single cast and the most houseguests in "Big Brother" history!

Love is in the air as a new season of the hit reality series "Big Brother" begins tonight on CBS.  This year the twist is "'Til Death Do You Part" as the house is packed with single men and women looking to get matched up with their "soul mate".

It's a landmark in "Big Brother" history - kind of "The Bachelor" meets "The Real World!"

Here's how it's going down:

When this group of 16 singles enters the house, they will be told they are being matched up with their "soul mate," a stranger who may prove to be their true love or their worst nightmare.  Whether there is a love connection or not, once paired up, the Houseguests' life in the game depends on their partner.  They must strategize, plot and scheme together as a couple for a chance at the prize.  These "lovebirds" will live together as a couple meaning they will sleep in the same bed, hold Head of Household as a couple, be nominated for eviction as a pair, and if the time comes, say their goodbyes together upon eviction.

There's a Grand Prize of $500,000 and a second place prize of $50,000 up for grabs, so you know some contestants will be asking, "what's love got to do with it" when they stab their partners in the back!

In addition to catching "Big Brother: 'Til Death Do You Part" on TV three nights a week, (Tuesdays, Wednesdays and Sundays), you'll also be able to follow the contestants 24/7 on the live camera feeds at CBS.com.
