Amy Winehouse went berserk outside a London prison yesterday, after her husband demanded a divorce. The troubled 'Rehab' singer lashed out at photographers outside Pentonville Prison following the tense meeting with Blake, who is currently on remand on charges of attempting to pervert the course of justice and grievous bodily harm (GBH).

Amy, 24, was so out of control police were forced to escort her back to her waiting car. A source said: "Amy just snapped and started shouting and screaming at everybody. She was out of control and even squared up to the photographers as if she wanted a fight."

"Whatever Blake said to her inside obviously upset her and she was in no mood to have her picture taken."

Earlier this week, Amy's father Mitch revealed Blake was under pressure from his mother Georgette to sever all ties with the troubled singer.

Mitch said: "Blake threatened to issue divorce proceedings when they were having a row."

"Unfortunately, Blake is influenced by things his mother has said. I think Georgette wants them to divorce, but it's up to them. From Amy's point of view, she would stick by him not matter what."

"But he has said things like, 'I want a divorce.'"
