"We e-mailed yesterday," she tells E!'s Daily 10 on Wednesday. "It's absolutely not true – and he's a great guy. I've worked with him for five years."
Duhamel has vigorously defended himself against allegations by Nicole Forrester, a stripper in Atlanta, who said she had sex with Duhamel one night at the St. Regis Hotel. Forrester also sold her story to the National Enquirer for more than $20,000.
Duhamel and wife Fergie's reps have denied the allegations. "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. "This story is absolutely ridiculous."
According to Sims, Duhamel and Fergie are the victims of someone, "[who's] trying to make a lot of money." "Josh is a great guy," she says, "and it's sad 'cause his wife is amazing, too."
