Britney Spears has been told she may not visit her two young children until she complies with court orders, a Los Angeles judge has ruled.
Ms Spears lost custody earlier this month
The 25-year-old had been granted monitored visits after losing custody to former-husband Kevin Federline.
But after an emergency hearing on Wednesday, judge Scott Gordon said they had been halted "pending Ms Spears' compliance with the court orders".
It is not known which directives the singer has failed to adhere to.
Judge Gordon has previously reprimanded Ms Spears for not complying with previous court orders, repeatedly saying that the custody order granted to Mr Federline resulted from her own choices.
Last month, the same judge said Ms Spears showed "a habitual, frequent and continuous use of controlled substances and alcohol".
She was then ordered to complete random drug and alcohol tests twice a week, as well as meeting weekly with a "parenting coach", according to court documents.
The judge also told Ms Spears and Mr Federline to complete a parenting class.
Also last month, Ms Spears was charged for allegedly crashing into a parked car while driving without a valid licence.
Federline won full-time custody of the children earlier this month
The singer is due to appear in court on 25 October in connection with the offence.
She was accused of hitting the car and driving away from the scene in Los Angeles on 6 August. She has since applied for a licence.
Ms Spears lost custody of Sean Preston, two, and Jayden James, one, to Mr Federline early this month.
She was later allowed monitored visits with her children as long as a parenting coach was present. The coach participated in the emergency hearing Wednesday.
The next hearing is scheduled for 26 October.
Mr Federline's lawyer said he had agreed to the terms, provided there were "assurances in place that made him feel the kids were protected".
A message left with Ms Spears' lawyer, Anne Kiley, was not immediately returned, the Associated press news agency said.
