They’re not the Brady Bunch….but they’re definitely one of Americas most well-known families!

In an interview Monday night on ABC News’ “Nightline”, the Kardashian girls let it all unravel in an exclusive 1-on-1 with reporter Cynthia McFadden. The sisters: Kim, Khloe, and Kourtney, along with their mother Kris Jenner, covered everything from their reality TV show “Keeping up with the Kardashians to Kim’s sex tape with singer/actor Ray J.

For quite some time now, the family has received much criticism and speculation from the tabloids and other media circuits about their “in the spotlight” lifestyles, but despite that, the K’s surprisingly still manage to keep up their mainstream appeal and flourishing business empires.
