I honestly wouldn't recognize any of the Kardashians if I tripped over them on the street.
What are they famous for? The dad was an athlete and one of the girls had a sex tape, is that it?
Stepdad of the older three and birthdad of the two teenagers is an Olympic athlete who unfortunately had one or several too many plastic surgeries. Bio-dad of the older three was one of OJ Simpson's attorneys. Mom is media-savvy (aka media-whore) who gets them all into the tabloids and Kim is the one with the sex tape. They're known for being able to get their faces in front of cameras, having money, being media-savvy - and the Kardashian-Jenner names, of course.
It's so sad that I know that and I don't even follow them or watch their shows. Kim shows glimmers of being gorgeous when she's not dressing trampy and the Jenner girls are going to be stunners, one in particular (can't remember which one but one of the two Jenners).
