Before she won an Oscar, Theron modeled lingerie and worked the catwalk in Milan.

Right after strutting his stuff in tighty whities in Risky Business, a young Tom Cruise flashed his guns—and an early prototype of his patented grin—for the camera.

Ashton Kutcher, 1995
Demi Moore, 1981

Brad Pitt, 1988
Someday, people would actually want to see this man with his shirt off. But doing this hokey-pokey pose was a good gig for struggling model-actor Pitt. Another job? Chauffering a limo for a strip-o-gram service.

Nicole Richie vs. Paris Hilton, ca. 1991
Back when life was simple, Hollywood curiosities Hilton and Richie were, in their words, "best pals since we were babies" at the Buckley School in Sherman Oaks. What did the divas-in-training do for fun? Play soccer.

Star Jones, 1995, vs. Barbara Walters, 1967
Once known for battling lawyers, not cohosts, as a full-figured Brooklyn assistant D.A., Jones still regards her former boss, '60s and '70s Today show anchor Walters, as "everything I want to be in a broadcaster."
