Kristin Cavallari Bikini Pictures: Staged, Still Hot

We were under no delusions that The Hills was real, or anything close.

But when its star wants out and a new troublemaker - who has not been seen nor heard from in years - mysteriously "joins the cast," walking in on the season's climactic scene no less, any trace of believability was pretty much jettisoned.

The question is, does anyone care?

Lauren Conrad's replacement, Kristin Cavallari, is already shaking things up on screen, as evidenced by MTV's new Hills trailer, and off screen, it did not take her long to channel her inner Speidi. Check out this hot, staged bikini photo:

Kristin Cavallari frolicks in the surf on a secluded St. Maarten beach. Well, almost secluded. Who would have guessed a photographer happened to be there!

Heidi Montag would be so proud - except that Kristin obviously needs bleached hair and major plastic surgery before truly attaining Heidi's fame whore status.
