Black was the color of choice for the Kardashian clan at the Los Angeles premiere of "The Twilight Saga: Eclipse" on Thursday.  Kourtney opted for a gray and black animal print, while Kim, Kendall and Kylie wore solid black to the event.

Kim, easily the most popular Kardashian, has been in the news lately for her budding romance with Dallas Cowboys wide receiver Miles Austin, 26.  "They are dating," says a source close to her, "but she doesn't want to rush anything." Another Kardashian friend tells Us Magazine, "Kim wants to date someone who gets her busy lifestyle."

Kourtney is currently starring with her sister Khloe (who was not at the premeiere) in season two of "Kourtney and Khloe Take Miami." The E! show features the two working at their second DASH boutique by day and living it up on the social scene by night.
