Back in the 1980s, you couldn't walk past a newstand without seeing a photo of Paulina Porizkova.
The Czech-American beauty graced the cover of Sports Illustrated's Swimsuit Issue back-to-back ('84 and '85) along with countless other magazines.
In the last couple years, she's dabbled in reality TV: with a short-lived stint on "Dancing With the Stars" (she was voted off first in Season 4) and judging three cycles of "America's Next Top Model."
The 46-year-old stepped out Wednesday to celebrate the 20th anniversary of Avon Anew looking better than ever in a plunging black dress. The timeless beauty told Beauty Counter that she's never gone under the knife but is a self-proclaimed "makeup and product whore."
