AINT THAT A B!TCH! JESSE JAMES HAS BEEN CHEATING ON SANDRA BULLOCK WITH SOME TATTED UP CHICK WHO USED TO BE A STRIPPER!

The tattooed mistress coming between Sandra Bullock and her bad boy husband is no Miss Congeniality.

Michelle (Bombshell) McGee has worked as a stripper at several San Diego clubs, according to Radaronline.com.

McGee, a mother of two, says she's been sleeping with the Oscar winner's hubby biker Jesse James - and that he said his marriage was "just for publicity."

A friend of McGee's told RadarOnline.com she knew of the 11-month affair.

"She told me that Jesse's marriage to Sandra Bullock was for publicity, and that's why he did Donald Trump's show, Celebrity Apprentice. He never called on Sandra for money or influence because their marriage was a sham," said Danielle Dee Madrano, owner of the adult web site SocalGlamourGirls.com.

McGee, who was raised Amish, was fired from the Hustler club about two years ago and now strips under the name Avery at a Pure Platinum Club in San Diego, RadarOnline.com reported.

James, 40, was married twice before landing America's sweetheart - including a two-year marriage to porn star Janine Lindemulder. The couple has a daughter named Sunny.

A source told RadarOnline.com they had never seen Jesse in the strip club.
Bullock, 45, moved out their Southern California home just days before the affair became public, People.com reported.

She also canceled her appearance at the London premiere of her Academy Award-winning movie, "The Blind Side."

On March 7, she won best actress for the role.

"Due to unforeseen personal reasons, a trip abroad to support 'The Blind Side' has been deemed impossible at this time," Warner Brothers said.

Bullock was also honored with a Razzie this year, for worst actress in "All About Steve."

In January, she gushed over James when she won a Golden Globe, telling him in her acceptance speech: "I love you so much and you are really hot. I want you so much." And the two were cozy at the Academy Awards.

Bullock and James met in 2004 when Bullock toured the set of James' TV show, "Monster Garage," with her 10-year-old godson. They tied the knot in 2005 at a ranch north of Santa Barbara.

Bullock spoke out recently about James' nasty custody battle. He won custody last year and she has played an active role in raising her. But McGee said James told her his marriage was over.

"I would never have hooked up with him if I thought he was a married man," McGee told In Touch Weekly. "He gave me the impression they were separated."
She said she met James at his motorcycle shop in Long Beach, Calif., while Bullock was in Atlanta filming "The Blind Side."

She went there for a late-night "photo shoot," then James took her to his office, she said.

"We ended up on the couch," she said. "He wanted to watch movies, but I asked him, 'What's going on with you and Sandra?'"

"'She doesn't live here. She has a house in Austin. She is filming, and I can't talk about it,'" James reportedly told her.

They had sex "two or three times" in his office that night, she said, and have been sleeping together for nearly a year.

Spokesmen for James and Bullock did not return calls for comment
