Audrina Patridge is back doing what she does best: looking hot in a bikini in Vegas. In fact, I'm pretty sure she can't do anything else, besides look like an airhead on The Hills. But that's fine, it's not like anyone's asking Audrina for her plan to solve the energy crisis, or to write a treatise String Theory. Though you've got to admit she is smart in at least one way: She's definitely getting her money's worth from those fake breasts.
