Kat Von D may have a new relationship with Jesse James, but that didn't stop her ex-husband from telling all about his former wife.

"She's the most self-centered person I've ever been involved with," Oliver Peck told In Touch Weekly. "Toward the end of our marriage, she was wanting to get liposuction, and she was taking drugs in order to lose weight."

The couple were married from 2003 to 2007, and Peck claims he tried to stand by her during her struggles with alcoholism.

The reality star often "got to the point where she was drinking until she was throwing up every day," Oliver said.
