Janice Dickinson looks fantastic ... when surrounded by seven hot models in bikinis.

Before scaring people on Hollywood Boulevard by running around in her underwear, the 52-year-old "supermodel" was at the beach yesterday, frolicking in the sand and getting wet (ick!) with some girls from "The Janice Dickinson Modeling Agency."

While the other gals showed off their killer bodies in skimpy two-pieces outside of the Silver Spoon BeachBody House, Janice thankfully kept somewhat covered ... looking pretty damn good -- for her.
