Melbourne, Nov 21 Fergie is trying hard to save her 11-month-marriage with Josh Duhamel by supporting him over allegations that he had a one-night stand with a stripper.

Exotic dancer Nicole Forrester, 34, alleges that the actor seduced her following a series of lap dances at the Tattletales strip club where she performs.

While Josh has denied the claims, Nicole has even reportedly passed a lie detector test undertaken by an expert.

But a representative for Josh issued a strong denial.

"This isn't 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. This story is absolutely ridiculous," the Daily Telegraph quoted the rep as saying.

The Black Eyed Peas singer has since dismissed the cheating reports as 'nonsense'.

While Fergie's pals have said that she broke down in tears after learning of the story, a source close to the star has claimed that she's been rocked by the claims.

"To say this has thrown her marriage into crisis is an understatement. But Fergie's a tough girl and she's determined to pull through. She's sticking with Josh and has decided to back him to the hilt.

"She's told those closest to her: 'There's no way I'm going to let this man go. I love him and he's too important to me,'" the friend told the News of the World. (ANI)
