1999: REBECCA ROMIJN

After Romijn joined MTV's House of Style in 1998, she landed her first SI cover (another would follow in 2006) and married John Stamos. Though she had a successful modeling career throughout the '90s, by the 2000s she was acting, landing roles in X-Men (and its sequels) and ABC's Ugly Betty. She divorced Stamos in 2004 and soon after married actor Jerry O'Connell; now 40, she's busy as a mom to the couple's twin 4-year-old girls.
