Kat Von D is hearing a lot of that lately as she took to facebook and twitter to say that she recently encountered the 19th woman Jesse James slept with while they were together.  Although Jesse had cheated on Sandra Bullock, she thought she was different.  "There was a time when I was confident and excited at proving the world wrong, because I believed so deeply in people's ability to change for the better. ... I did feel like it would be a positive thing for those who judged Jesse solely based on what they read in tabloids, to see that change is always possible."  She says she still believes in love and while she believes she made a mistake, she has learned from it.  So do you believe the saying to be true, "once a cheater, always a cheater?"
