For some reason or another, the fashion icon that is Paris Hilton is so stressed (must be all that partying!) that she needs to use multiple layers of deodorant to prevent her from smelling bad when she attends parties like last night's.

Paris put her best clothes and face on, and drove to her CD launching party that took place last night at a posh club in Los Angeles. Because we all know how much everybody loves the naughty heiress, it's no wonder that tens of paparazzi gathered at the gates of the establishment to see her and to talk to her.

But the first thing that caught their attention was (no, not her underwear or the lack of it) but her armpits, which were so heavily covered with solid deodorant that it could easily be seen even without her raising her arms.

Later in the evening, Paris went and took over the controls and played the DJ on her tracks. And, as it is customary at any respectable party, the roof was raised many times. Too bad she didn't think twice before lifting her arms or, at least, before using whatever she used to prevent sweating...

From now on, probably Miss Hilton will weigh her words better before lashing out on anybody who's anybody. You know what they say, the pot should never call the kettle black, or white, as the case goes...
