Yuvraj singh appearence on Kim Sharma party

We wonder what's up with Kim Sharma and Yuvraj Singh? Apparently Kim Sharma and her good friend Preeti Jhangiani were enjoying hemselves at a recent [arty, and that's when Yuvraj Singh decided to make an appearence. But it was the shortest appearence by Yuvraj singh we know. He took one look inside and zoomed off again. We wonder why? Was it because of the paparazzi hanging around or some other reason.
