When you're going to do the Beyonce pit pose, you better make sure you're groomed first.

Paris Hilton has a 5 o'clock shadow and it's not on her face. The dancing diva is caught in the act of waving her arms - as she is prone to doing while busting a move. It looks like the pampered celeb forgot her grooming on this occasion because her stubble is glaringly apparent - and she told us she was a natural blonde.

This is really a shocker to me. I'd expect a superficial snob like Paris to always get it right. She's been photographed forever and she knows the flashing bulbs are gonna go crazy when she's around.

This is what happens when you're too busy sucking cocks the night (and day) before getting dressed from some random dude's room before making a few stops and heading to another bash. I hope she's embarrassed.
