Now THAT'S hot!

Either Paris Hilton needs to come out with an ab exercise video, or she's just genetically blessed, but either way, her toned tummy looked amazing when X17 photographers snapped her running errands in Los Angeles on Monday. P stopped by Barneys New York with her adorable pooch, and after that she grabbed a bite to eat at Lemonade.

But are we allowed to pinch her for not wearing any green on St. Patrick's Day? We're pretty sure she changed into something a little more festive later on though...
