Happy 50th birthday, Elle Macpherson! The Australian supermodel known as The Body is entering her fifth decade and she’s still catwalk-ready. The former Sports Illustrated model—she graced the cover of the Swimsuit Issue a record six times!—has brought her modeling know-how to Britain & Ireland’s Next Top Model, which she hosts and executive produces. Early on she was also the season 1 host and executive producer of NBC’s Fashion Star.

A savvy entrepreneur—or an “accidental executive” as she once called herself—with a net worth of $60 million, she has a number of ventures, including the successful lingerie line Elle Macpherson Intimates, On Cloud Nine women’s underwear line and her Elle Macpherson—The Body beauty products. The stunning Aussie and mother of two (to sons Flynn and Cy, with financier Arpad Busson) is also no slouch in the do-gooder department. Along with serving as the global ambassador for Australia’s Smile foundation, helping families of children with rare diseases, she’s involved with RED, an initiative started by U2’s Bono and activist-attorney Bobby Shriver to raise awareness for the Global Fund, which works to prevent and treat HIV and AIDS, tuberculosis and malaria around the world.
