Tattoo Model Knew Jesse James Was Wed to Bullock During Alleged Fling

 SoCal Glamour Girls/Splash News

Tattoo model Michelle McGee claims she didn't know Jesse James was still with Sandra Bullock during their alleged 11-month fling. But McGee's former boss claims otherwise.

Last year, while posing for the Southern California-based modeling site SoCal Glamour Girls, McGee openly talked about her times with James, 40, SoCal owner Dani Madrano tells (James has not responded to McGee's infidelity claims, but he has publicly apologized to Bullock, 45.)

Madrano says she remembers when McGee first told her about meeting James at a strip club. "I said, 'Wait, a minute — isn't he married to Sandra?'" Madrano recalls. "And that's when she told me, 'Oh, well. That's just a sham for publicity.'"

That's why James didn't use Bullock, 45, as a contact on Celebrity Apprentice last year, McGee explained to Madrano.

"'I'm his girlfriend,'" Madrano recalls McGee telling her.

When she was with James, McGee often got "mad" at him because "they were either supposed to spend time together and didn't, or I think some follow-up from him wasn't there," Madrano tell Us.

Madrano says McGee often retaliated, saying things like: "'Fine, then the next time you want me around, I'm not gonna be there!'"

McGee reportedly earned $30,000 for talking to In Touch about the affair (the tabloid has not commented on those reports).

But Madrano tells Us she isn't sure if McGee did the interview for fame.

"I can't get inside of Michelle’s head," she tells Us. "I do think that she really likes him, knowing what I know about Jesse and knowing Michelle personally. If Sandra was out of the equation completely — or, I should say, never in the equation — I think that Jesse and Michelle [would be] good together. They just seemed to fit, based on personality and looks. But I don't know Sandra, and I'm not saying anything bad about her because I know she is 'America's Sweetheart' and she is awesome."
