Twitter row over Michael Jackson's medication ends up in legal threats

Debbie Rowe threatened to sue Michael Jackson's doctor over accusations she stole Demerol to supply to the late star.

The 54-year-old nurse got involved in a bitter war of words with dermatologist Dr. Arnold Klein - who introduced Debbie to Michael after being employed as a nurse by him in the 1980s - on Twitter, after he alleged she took the powerful painkillers from his practice to feed the singer's addiction.
