Attorney Romin Alavi tells Us Weekly, "Josh bragged about what happened on the set of his movie [Life As We Know It], and someone called the Enquirer with the tip. The Enquirer then came to Nicole."
The actor's rep dismissed the fling.
"This is not the first nor will it be the last time that a stripper was paid a large amount of money to sell a false story about a celebrity," Duhamel's rep said in a statement. "This story is absolutely ridiculous."
Forrester claims that Duhamel introduced himself as a porn star named "J.D." at the Tattletales Lounge, where she worked as an exotic dancer. She alleges the two had sex a few days later.
