Debbie Rowe filed a defamation lawsuit against Rebecca White, after the woman went on “Extra” and claimed to be a close friend of the birth mother of Michael Jackson’s two oldest children, TMZ says.

White had said on air that she had an email from Rowe indicating she wasn’t interested in custody of her children. The emails don’t exist, Rowe claimed.

She charges in the suit that White has inserted herself into numerous celebrity stories, claiming that two models forced her to smuggle drugs, and that she saw Heath Ledger using cocaine before his death.

Meanwhile, the L.A. County Coroner’s office said it needs two more weeks before it can release Jackson’s autopsy report, TMZ says.
