A San Diego-based tattoo model, McGee claimed to have had a months-long affair with Jesse James, the husband of recent Oscar-winner Sandra Bullock.
In a statement to PEOPLE, James says the "vast majority" of the allegations are "untrue and unfounded," but he also apologized to his wife and children "for my poor judgment." Bullock left the family home just days before the allegations surfaced, a source tells PEOPLE.
Hard-Partying Lifestyle?Who is Michelle "Bombshell" McGee? What little she's said about herself comes from the most unreliable of sources: profile blurbs and videos on adult and edgy Web sites. But one thing is constant: she projects the image of a woman with a hard-partying lifestyle.
On SoCalGlamourGirls, where users can pay to see her on a Web cam or chat with her, McGee's page says: "Sure, I get really wild in the sack with my men, but I'm actually a graduate student in college looking for the right sugardady [SIC] to teach me and be my sexy mentor."
McGee, whose age is listed as 24, claims she has a bachelor's degree in biology and finished two years of medical school. "Now, I especially love to have affairs with doctors," her page reads. "Their medical talk makes me hot! I love to be challenged, and I love to put know-it-all doctors in their place."
Other online photos of McGee show her in various semi-nude poses. In one, she's eating candy hearts from a pink dog bowl; one on the home page of her Web site shows her standing in heels and underwear in a coffin. Another photo shows her getting one of her buttocks tattooed.
On the SoCalGlamourGirls' site she claims to be French-Canadian. But in an Internet video highlighting a tattoo contest, McGee said she "grew up Amish" with "very conservative" parents who "don't talk to me, but it's okay – I have good friends." McGee said she got her first tattoo at age 15, then "left the church when I was 16 years old and never looked back. I moved out to California and I got tattooed, never looked back."
Another Side to HerBut some say there's another side to her. On her Twitter page, which has an unprintable moniker, in between posts about stripping at the Platinum club in San Diego, are references to her children. People have said she spoke of two sons who she doted on.
"She was very down-to-earth, very friendly ... very easy to talk to and very likable," says Rich Peterson, owner of Konformity Clothing, for which McGee modeled in exchange for clothes, including some in child sizes, apparently for her kids.
Danielle Medrano, founder of SoCalGlamourGirls.com, says McGee mentioned after a photo session last summer that she was dating James.
"She definitely told me they had good chemistry and they got along really well and he was super duper sweet," says Medrano. But what McGee most talked about were her own children.
"She lives for her children, she loves them and is very close with them," says Medrano. "I can tell you she loves them. When she started working for me she bought her boy a hairless cat. [She said:] 'It was cute, look at him, isn't he cute, he's great with her kids.' "
