Sadly, the sexy Bad Teacheractress, 39, probably didn't win any costume prizes that night.

Perhaps assembled last-minute, Diaz's ensemble consisted of skintight leather pants, boots, a cleavage-baring black top and blazer. The tell-tale stripper props? A sexy belly chain -- and plenty of dollar bills tucked into her waist!
