45-year-old PAMELA ANDERSON got back into her "Baywatch" bathing suit in Rio last week to film a TV commercial.  It's been 15 years since she left the show.  Can she still rock it?  YES OR NO? 

(--I'm gonna have to say NO.  For her age, sure, she's a looker.  But when she puts on that bikini, you automatically compare her to her younger self . . . and she just doesn't hold up.)
