Keeping up on her fabulous physique, Audrina Patridge was spotted being escorted to her car by her personal trainer after a session at the gym on Tuesday (November 10).

The brunette beauty couldn't stop smiling as she walked alongside her fitness guru, giving him a big hug goodbye before driving off.

In related news, it was just reported that Miss Patridge's "Hills" co-star, Kristin Cavallari, is now dating her ex-boyfriend, Tal Cooperman.

An inside source told press, "It's brand new. They're having a lot of fun enjoying getting to know each other better. It's not for the show. They hit it off and have been hanging out off-camera."
