Hilary Duff left through the back entrance of Curve Boutique in West Hollywood with her boyfriend in Los Angeles. There is officially no point to the back entrance. More paparazzi wait back there than in the front. They need to come up with secret roof top escapes with helicopter pads fully equipped and ready to go. Ah,who am I kidding? Even then the paps will find a way to get the shot.

Maybe the back entrance exit is so it looks like they didn't want to have their photo taken?
