When Sandra Bullock thanked her bad-boy husband, Jesse James, as she accepted her best actress Oscar for The Blind Side, she may not have known that while she was away shooting the film, Jesse was carrying on a steamy affair with a tattoo model. While Jesse has had an 11-month affair, including five weeks of sex, with Michelle “Bombshell” McGee, she believed he and Sandra were no longer together. “I would never have hooked up with him if I thought he was a married man,” Michelle tells In Touch in an exclusive interview. “He gave me the impression they were separated.” For weeks, while Sandra was in Atlanta shooting The Blind Side, Michelle had sex at least once a week with the Monster Garage star. Far from a one-night stand, his relationship with Michelle was intimate and highly charged. Michelle even says she called Jesse, who didn’t wear underwear or condoms, by a special pet name, Vanilla Gorilla, because he was so “well-endowed.”At least you still have Oscar!
