Robbie Williams has checked out of rehab a week early, despite medical advisers urging him to finish the four week programme.
According to The Sun, Williams was staying in the Cottonwood de Tuscon rehab centre, which is one of the harshest in America.
Williams is reportedly back in LA, where his mum Jan � a drink and drugs counsellor � is helping him battle his demons.
Robbie�s spokesperson confirmed he had left the rehab facility.
