Oliver Peck — who owns Elm Street Tattoo in Dallas and was married to Kat Von D from 2003 to 2007 — tells In Touch in an exclusive interview, “She’s the most self-centered person I’ve ever been involved with.  Toward the end of our marriage,” Oliver claims, “she was wanting to get liposuction, and she was taking drugs in order to lose weight.”

In what has to be one of the most dramatic before and after images, Peck submitted a photo of his then-wife (at what, 50-pounds heavier?), and wonder how many other personalities live inside the former Katherine Drachenberg.

Her newfound fame changed her in other ways, too.  Kat “got to the point where she was drinking until she was throwing up every day,” Peck says of the 28-year-old, who finally got sober in 2008. “She’d be incoherent and sometimes destructive.” Oliver claims he tried to stand by her — until a friend told him “she was having an affair.”

The idea of a marriage-ending affair is ironic, considering that her new boyfriend is one of Hollywood’s most notorious cheaters.  “Kat and I met Jesse (James) and Sandra (Bullock) about four years ago at a party,” reveals Peck. “Kat said she thought Jesse wasn’t very cool.” James is now Von D’s new gentleman-friend.
