Anna Malova is being held without bail at least until her court date next week. Authorities said Monday that she had been causing trouble in rehab.
Malova has been charged with repeatedly forging prescriptions to get painkillers. She'd been on track to get the charges dismissed if she successfully completed drug treatment.
But she could be tried if a judge ultimately determines she has failed at rehab.
Malova was a doctor in her homeland. She was named Miss Russia and finished in the top 10 in the Miss Universe pageant in 1998.
