Nicole Forrester -- the stripper who claims she had an affair with Josh Duhamel -- has reached out to "Extra" to apologize to Fergie.

"I thought, 'Nobody's gonna find out. It's not gonna hurt anybody," says Forrester, a 34-year-old single mother of two who says she slept with Duhamel, 37, while he was filming "Live As We Know It" in Atlanta. "I'm sorry. I'm sorry that I didn't think of it at the time like I think of it now."

Duhamel, for his part, has vehemently denied her story.

Forrester fumes that she's been labeled a home wrecker.

"She's standing by her man, so obviously I'm not wrecking the home too bad, huh?" she says.

But she's been facing public wrath.

"My son, he went to a football game last Saturday and he was like, mom, 'you're disgusting. I didn't know you had sex with him,'" he says.
