Thankfully Sandy has her Blind Side Oscar to console her...

According to the new In Touch Weekly, bad boy Jesse James has been having an eleven-month affair with Michelle "Bombshell" McGee, a tattoo model from San Diego. Apparently, this also includes "five weeks of sex."

It all started when wife Sandra Bullock began to shoot The Blind Side in Atlanta - Michelle friend requested Jesse at West Coast Choppers in the hopes of snagging a modeling gig and drove out to LA to meet him...

Says Michelle: "I asked him, 'What's going on with you and Sandra?' And he said, 'She doesn’t live here. She has a house in Austin. She is filming, and I can’t talk about it."

The tattoo model also reveals to In Touch that Jesse didn't wear underwear... or condoms... and that she nicknamed him "Vanilla Gorilla."

Hmm, can this really be true? Sandra thanked Jesse so lovingly in her Oscar acceptance speech. Does she know?
