Paris Hilton is confused. And why shouldn't she be? Cocaine does bear a striking resemblance to chewing gum. So it would be natural for her to think a little white baggie of the former, which fell out of her purse during a traffic stop last weekend, was actually the latter. Wouldn't it?

The 29-year-old hotel heiress and her nightclub owner boyfriend Cy Waits were pulled over in Las Vegas because officers said they smelled marijuana smoke wafting from their car. Not only did Hilton claim the bag containing .8 grams of coke wasn't hers -- nor was the purse because it was "too cheap" -- she also said of the mysterious substance that "she had not seen it but now thought it was gum," according to the police report. The authorities didn't buy it and charged her with felony drug possession.
