Sandra Bullock and Jesse James

Sandra Bullock's husband Jesse James may be cheating on the Oscar winner with an alleged mistress who goes by the oh-so-imaginative nickname "Bombshell" (proper name Michelle McGee).

In a revelation that makes good on the rumors that the best actress award is a marriage curse (thanks Kate and Sam), the web is buzzing with rumors that Jesse James has been sleeping with the tattoo model for nearly a year.

The story -- or should we still say allegation -- was broken by In Touch, which features an exclusive interview with the alliterative mistress this week, claiming she never meant to be the other woman.

Says McGee, “He gave me the impression they were separated."

Apparently McGee missed all those stories about The Blind Side actress standing by her man while he fought for custody of his daughter and looked for his lost dog?

Sparing no details about their sex life -- right down to the decision not to use protection -- McGee tries to play herself as a wronged woman in this situation. Apparently she thinks the little golden statuette already has Sandra's back.

If the stories are true, we feel especially bad for James' daughter -- first one tumultuous family drama, now another? Can this little girl ever catch a break?
