More revelations are emerging about the “bombshell” dropped on Sandra Bullock’s marriage. After tattoo-covered “glamour” model Michelle “Bombshell” McGee came forward to say she had an affair with the Oscar winner’s hubby, Jesse James, a friend of hers told Radar Online that their relationship was far from secret — and she believed the couple’s marriage was a sham.

“She told me that she and Jesse were together. This was around May 2009, or just prior to that,” said the friend, who added the affair lasted nearly a year.
