Kourtney Kardashian is already a reality television star, but now she's taking on scripted parts! The eldest Kardashian made her acting debut on ABC's soap opera One Life to Live this week, where she played personal injury lawyer Kassandra Kavanaugh (with two K's of course!). Kardashian's character was arrested with Christian Vega (played by David Fumero) after they both got into a fight with the same guy at the gym, which explains her orange-and-gray workout ensemble shown here. Catch Kardashian on the season finale of E!'s Kourtney and Kim Take New York this Sunday at 10/9c, and watch her soap opera appearance in a clip after the jump.
