Jesse James Engaged: Michelle Bombshell McGee Warns Kat Von D

"Once a cheater, always a cheater." That is an age-old adage that Jesse James' former mistress Michelle Bombshell McGee believes in. Michelle shared some of her feelings on Jesse's engagement to Kat Von D, personally addressing the L.A. Ink tattoo maven about her decision to marry someone who has a poor track record when it comes to fidelity.

"Kat what in the world are you thinking?" Michelle Bombshell McGee told Radar Online, via the Huffington Post. "I was with Jesse during his marriage — the guy's not faithful, he doesn't have a faithful bone in his body!"

Michelle continued on her rant, calling her former flame a pig.

"If he did it to me, if he did it to Sandra, he's gonna do it to you, too — once a cheater always a cheater," she said. "He cheated on his wife, numerous times."

Jesse’s engagement to Kat comes less than a year since his split from Sandra Bullock — their marriage collapsed after his infidelity went public last March. Their divorce was finalized in June and he began dating Kat that summer.

This will be Jesse's fourth marriage, and it certainly seems like Michelle, who once told OK! she was happy for the couple, has really changed her feelings on Jesse.

“There are no hard feelings towards Jesse,” she old OK! last summer after news of his relationship with Kat went public.

"I just always wish him the best with Kat and everything,” she explained of her former paramour. “I kind of joke around with Kat, but I have no hard feelings or anything.”

Jesse and Kat confirmed their engagement yesterday on Twitter, and according to Radar, the couple wants to make their relationship official and planning to wed as early as next month.

Do you think Jesse and Kat are the real deal? Is their relationship bound to collapse eventually?
