Amy Winehouse collapses at home

Amy Winehouse is being treated for nervous exhaustion after she collapsed at home.

The troubled 'Back to Black' singer was treated at home by a doctor over the Christmas period as a chest infection coupled with the stress of her recent arrest on suspicion of assault both took their toll.

The singer's friends have been keen to stress Amy is not back on drugs and isn't drinking heavily, although work on her comeback album will suffer setbacks as she recuperates.

The source added: "Her new songs are amazing but will be on the back burner until she feels better."

Amy's recent arrest - for allegedly attacking a theatre manager at a performance of 'Cinderella' in Milton Keynes, England, on December 19 - has led to her being charged with a public order offence and common assault.

She will appear at Milton Keynes Magistrates Court to answer to the charges on January 20.

The source said: "The last week has been a massive setback for Amy, who was really turning a corner. Everyone in her camp is shocked by what has happened.

"The New Year doesn't look set to get off to a good start, but Amy is determined and she'll keep looking forward."
