There may be some credence to Life & Style’s claims that Sandra Bullock’s husband Jesse James cheated on her with a dominatrix, because she’s suddenly pulled out of all upcoming promotional obligations and he’s gone and deleted his Twitter account. Star Magazine says

Michelle ‘Bombshell’ McGee claims she carried on an 11-month affair with the West Coast Choppers guru, including five weeks of sex — which took place while Sandra was on the Atlanta set of Blind Side. The San Diego-based tattoo model claims Jesse texted her as recently as March 14th.

Hours after news of this alleged affair became public, Sandy — who’s raising Jesse’s youngest daughter, Sunny, whose mother is troubled porn star Janine Lindemulder — pulled out of the London premiere of Blind Side. A rep said she won’t attend the junket or premiere next week because she’s “unable to travel due to unforeseen circumstances.”

Meanwhile, Jesse — a frequent user of Twitter, which helped reunite him with his missing dog Cinnabun earlier this year — abruptly deleted his account which he had been posting to multiple times a day for at least the last six months under the handle @frankyluckman.

And just who is this Michelle “Bombshell” McGee? I’m glad you asked. According to Fox411

The tattoo model is featured on a site called SoCalGlamourGirls.com, where viewers can pay to see her on a webcam. “I am the hottest busty tattoo and fetish model you will ever meet on a webcam,” her profile reads. “Come have a hot and steamy affair with inked girls like me on live video.”

[She] also mentions her foot fetish and dominatrix work, stating “I mostly wear leather and chains for my video chat customers.”

McGee claims that she’s currently working on her Masters degree in biochemistry, stating that she has a BS in biology [and] also claims to have completed two years of medical school.

However, she’s listed as 24 years-old on the site, so unless she’s some kind of leather-clad Doogie Howser, that math just doesn’t add up.

The Best Actress Academy Award curse strikes again! Let’s see — there’s Reese Witherspoon, Hilary Swank, Charlize Theron and Kate Winslet, all of whose relationships hit the skids in the months following their Oscar win. And now Sandra Bullock, less than a week after she took home Academy gold! That category is relationship poison. You’d be better off winning an award for “inoperable goiter” and “chronic halitosis” than taking home an Oscar for best actress.

UPDATE: People Magazine is now reporting that Sandra moved out of the home she and Jesse shared on Monday. Also, I got my hands on some better quality pics of the whore (thumbs 2 & 3). Do you think she uses a Bic or a Sharpie to draw on those eyebrows?
