The celebrity cheater: Reality TV star Jesse James.
The other woman: Tattoo model Michelle "Bombshell" McGee.
What was gained: Undue publicity for everyone involved. America's sweetheart Sandra Bullock was blindsided and mortified by the news of her husband's year-long affair with a tattoo model just days after receiving the best actress Oscar for "The Blind Side." James and McGee cashed in on their 15 minutes, however; he with a tell-all book, "American Outlaw," and she with numerous talk show turns and an Australian "Sexpo" tour.
What it cost: Would you believe nothing? Despite James' attempt to save face by stating he would refuse spousal support (he is the CEO of West Coast Choppers after all), it really wasn't necessary -- by Texas law, you must be married 10 years to receive alimony.
