Karolina Kurkova has made it back to the catwalk. After a short-lived acting stint (2009's G.I. Joe: The Rise of Cobra) and giving birth to her first child with film producer Archie Drury, the 26-year-old supermodel has returned in top form. Thanks in part to some "funk cardio" with trainer Tracy Anderson, the Czech import strutted, and didn't slum it at all, for both Alexander Wang (pictured left) and today's Rodarte show. Bring it on.
