Jessica Simpson's groom-to-be was photographed in a Los Angeles alley Saturday, taking what can best be described as a skinny, hand-rolled cigarette from a pal.

Eric Johnson, a former pro football player, walked into the alley in an upscale residential neighborhood, before taking the single cig from his buddy.

If by some chance the cig in question is a marijuana joint -- and we're not saying it is -- possession of less than one ounce is a misdemeanor under California law, with a fine of  usually about $100.
