EXCLUSIVE PHOTOS - Pamela Anderson Pushes It Real Good

Pamela Anderson is back where she belongs ... the beach!

Anderson is in Malibu -- celeb summer hotspot -- and she picked up some groceries for her and her family.

Of course, while some celebs use Malibu to sport their finest fashions, Pam seems content in ... a big T-shirt?

And, of course, the makeup-less, au naturel look.
