The bikini bods are coming out in full force -- and Lisa Rinna is the latest to show off her impressive physique.

Following in the barely-clad footsteps of 38-year-old Tori Spelling, 41-year-old Denise Richards and 40-year-old Carmen Electra, the 48-year-old former "Melrose Place" star flaunted her abs in a two-piece yesterday in a Santa Monica park.

Rinna, who posed for Playboy when she was 45, clearly has no problem showing some serious skin ... but do you really blame her?
