Lee Grace Dougherty

Lee Grace Dougherty
Just days before the Dougherty Gang allegedly robbed a Georgia bank last week -- the lady of the bunch stripped down to her birthday suit for a hardcore photo shoot.

29-year-old Lee Grace Dougherty -- a sometime professional exotic dancer -- was approached by some friends who host poker games ... who asked if she would waitress at their events and pose nude for their promotional materials. Lee obliged ... and over the past 6 weeks, she posed for a series of VERY revealing pictures which give the term "photo spread" a whole new meaning.

One person connected to the photo shoots tells us Lee posed for some of the photos as recently as July 29, less than a week before the bank robbery. We're told Dougherty was not paid for the "modeling" work.

Days later, Lee became an overnight celebrity outlaw when she and her two brothers allegedly shot a police officer ... robbed a bank ... and went on the run while in possession of some high-powered firearms.
