Now Kim Kardashian, who has the same claim to fame as Paris Hilton (spoiled daughter of rich parents), is becoming popular and making her sister Kourtney Kardashian famous too for just being curvaceous brunettes who like to show off their perfect bodies on the beach or at nightclubs in Hollywood and Las Vegas. Why do we pay so much attention to sexy women?
