"She knows she made a mistake, but overall she's in a better place," says a close friend of Richie. "She has come a long way from her heroin days."
The celebutante is said to be upset over media reports that she's addicted to pills, and is insisting to friends that she only "occasionally" takes Vicodin once a month at the start of her menstruation cycle.
Richie is also unhappy that California cops listed her weight at 85 pounds on the police report because "she's so proud of her weight gain," says the source, who adds that Richie has gained about ten pounds in the last two months and actually weighs around 95 pounds. "She doesn't know where the cops came up with 85 pounds and it's annoying to her."
