The Sports Illustrated Swimsuit issue special aired on the Audience Network for the very first time in 2017. The Making of SI Swimsuit 2017, a 50-minute documentary, is exclusively available on DIRECTV NOW. The show, like the issue, celebrates the strength of women—in all forms. You'll see 63-year-old Christie Brinkley alongside her two daughters, Alexa Ray Joel and Sailor Brinkley Cook, plus elite butt-kicking athletes Serena Williams, Caroline Wozniacki, Genie Bouchard, Simone Biles and Aly Raisman. (They'll soon be joined by rookie Mia Kang, who announces that she's training to become a Muay Thai fighter.) Rookie Bianca Balti talks about being a strong single mother. You'll see ChrissyTeigen return to the world of bikinis for the first time after the birth of her daughter, Luna as well as 3-time S.I. swimsuit model Kate Upton.
