The woman whose identity Ashley Dupre stole to (falsely) state she was 18 before being filmed by Girls Gone Wild is now suing the ex-hooker.

Joe Francis has pictures and video of Ashley Dupre nude and in "sexual situations." She was suing to block its use, but she withdrew that claim.

Back in 2003, Dupre duped Girls Gone Wild producers by using Amber Arpaio as her alias, showing a New Jersey driver's license with the name.

Problem is, Amber Arpaio is a real person.

One who is claiming - in a federal lawsuit - that her once-innocuous name has been dragged through Ashley Dupre's trail of skankiness.

Ashley Dupre was a girl gone wild - using a fake ID of Amber Arpaio.

Amber's lawyer, Robert Dunn, said his client's DL got in the hooker's hands only by accident, whatever that means. Joe Francis had no comment.

Hopefully they get the footage of Ashley Dupre deciding how to deal with these various lawsuits on her reality show, that's all we care about.
