Katarina Ivankovska is a 21-year-old fashion model from Macedonia and, according to a tipster, the new girlfriend of Jets’ QB Mark Sanchez. After we linked to this page 6 item this morning, a reader wrote in claiming to have seen Ivankovska and Sanchez together at the gym multiple times. Said reader claims the buzz in the place is that the two are dating. We’re sure the Daily News or NY Post will break this one wide open tomorrow (or debunk it so that it falls in our “memorable gaffe” category.)

Here’s Ivankovska “supermodel” page. Previously, Sanchez dated model Hilary Rhoda (she’s with Sean Avery now), and a USC sprinter.
