NEW YORK, Feb. 18 (UPI) -- Sports Illustrated was not about to let their annual Swimsuit edition run without featuring their two-time cover girl Kate Upton. That is why the 21-year-old model once again landed the coveted honor -- this time, on the back of the magazine.
SI's 50th anniversary swimsuit cover features Nina Agdal, Lily Aldridge and Chrissy Teigen posing topless in tiny bikini bottoms, but Upton graces the back cover of the magazine solo posing on the beach in the Cook Islands wearing a revealing pink bikini.
