Amy Winehouse's marriage on the rocks

Amy Winehouse's marriage to Blake Fielder-Civil is reportedly on the rock, sources claim.

The troubled singer reportedly  went "ballistic" when she saw Fielder-Civil chatting 'intimately' with British supermodel Lily Cole at a party held in plush London store Harvey Nichols.

And, according to sources, Blake left the bash with Lily, leaving Amy alone for three hours before he returned to continue the argument.

A source said: "Blake and Lily were chatting very intently for ages before Amy arrived.

"Amy went ballistic when she saw them together and dragged Blake to the toilet to confront him. They were arguing for at least 20 minutes. Amy was shouting at him and asking him what an earth he was doing with Lily.

"Blake tried to explain but Amy was having none of it. People waiting to use the toilets were just standing their open mouthed. Their marriage is hanging by a thread."

The couple eventually sorted out their differences, but Amy is said to be fuming about the attention Lily gave Blake.

A party insider told British 'Mirror' newspaper:  "They managed to paper over the cracks enough to leave together but Amy was seething. There is no love lost between her and Lily."
