Audrina Patridge took time away from her busy life to get physical at the gym this afternoon (November 10) in Los Angeles.

After her session with her personal trainer was up, he escorted to her car where the two gave hugs as a goodbye — but could the two have some chemistry brewing?

Meanwhile, sources say Audrina is lauging off reports that her Hills co-star Kristin Cavallari is dating her other ex, Tal Cooperman.

An insider tells Us Weekly: “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.”
