Robbie Williams Leaves Rehab Centre

The Angel singer spent three weeks at an Arizona clinic for treatment for an addiction to prescription medication.

A spokesperson for the former Take That singer confirmed that he left the treatment centre a week early, but claims that Williams has entered an "after-care programme in Los Angeles".

This is not the first time that the British star has undergone treatment for the problem.  In 1995, he was treated for dependence on both drugs and alcohol.
