AMY WINEHOUSE - WINEHOUSE IN REHAB

Neo-soul star Amy Winehouse has checked into an expensive retreat in order to help her recover from her troubles with substance abuse.

The Sun reports that the Rehab singer has checked herself into the Causeway therapeutic retreat, which is located on an island an hour away from London.

Winehouse decided to seek private treatment after overdosing on a cocktail of heroin, ecstasy, cocaine, the horse tranquilliser ketamine and alcohol. She checked into the centre with her husband Blake Fielder on Monday, according to the paper.

The heavily-tattooed crooner has cancelled her scheduled performance at a Rolling Stones concert in Germany.

She had previously declined to perform at T in the Park, the Liverpool Summer Pops and the Oya music festival due to ill-health.

The earlier cancellation of her performance at the Norwegian music festival came after she received treatment at a London hospital for exhaustion.

Last week, Winehouse, 23, was nominated for three MTV video music awards.

Her album Back to Black has achieved great success in the US and the UK and she has been nominated in the female artist of the year and best new artist categories at the American music channel's award show.
