The Hills are alive with the sound of drama!

Kristin Cavallari is seeing ANOTHER one of Audrina Patridge’s former flings, Tal Cooperman.

A source tells Us Magazine:

Audrina thinks it’s laughable. Tal and Kristin have gone out a few times now, but it’s nothing serious. Tal and Audina never officially dated and are still friends.

Kristin must be loving Audrina’s taste in men, because she also had a short-lived romance with Justin Bobby. Another insider asks:

Why does she continue to chase Audrina’s sloppy seconds?"

Surprisingly, the castmates are on better terms now (despite Kristin’s boyfriend-stealing ways).
