Lauren Conrad, Audrina Patridge, Whitney Port Enjoy Some Fun in the Late Summer Sun

The Hills' fabulous trio - Lauren Conrad, Audrina Patridge and Whitney Port - stripped down to bikinis and had a blast at the beach in Malibu Wednesday.

No word on whether Justin "Bobby" Brescia was on hand, but Audrina sure looks to be having fun, as do her roommate / BFF LC and her co-worker Whitney.

Of course, professional party animal and JV womanizer, Brody Jenner, was also on hand, while Spencer Pratt and Heidi Montag were very much not.

Check out these photos of Lauren Conrad - whose fall fashion line will drop in just two weeks â€" and her gal pals enjoying some summer fun. They're so cute!
