Rehab singer said, "No..No..No"

TROUBLED AMY WINEHOUSE sensationally walked out of rehab yesterday — then took a helicopter to London for a brain scan.

The heroin and cocaine-addicted singer quit after less than 48 hours — despite her worried parents’ pleas to stay.

She left a clinic in Essex and flew back to Camden, North London, where she overdosed on drink and drugs eight days ago.

Later she and hubby Blake Fielder-Civil visited a private doctors surgery in central London — before planning a night out with pals.

Her worried parents Mitch and Janis are now considering getting her SECTIONED to force her into getting help for her problems.

Doctors ordered Amy, 23, to have the brain scan after she had a seizure during her overdose. It will reveal whether the singer has a form of epilepsy — which could have been undetected until now.

A source said: “The London clinic has specialists who deal with brain-related problems.”

Amy’s decision to leave rehab followed a huge rift between her husband and the rest of her family.

Dad Mitch and others close to Amy are desperate to get her away from him — because they believe he will stop her getting treatment.
