Amy Winehouse and Blake Fielder-Civil have had yet another explosive argument - this time it was over her husband's flirty chat with model Lily Cole.

At the launch for Mary-Kate and Ashley Olsen’s new fashion line, Amy arrived alone with her signature beehive and clutching a cigarette. Blake was already at the event and was getting rather friendly with Lily.

According to a source in the Daily Mirror: “Blake and Lily were chatting very intently for ages at the dinner table before Amy arrived. Amy went ballistic and when she saw them together and dragged Blake to the toilet to confront him.”

Another eyewitness says: “Amy was shouting at him and asking him what on earth he was doing with Lily. Blake tried to explain, but Amy was having none of it. People waiting to use the loos were just standing there open-mouthed.”

An insider close to the couple claims that the couple who married in May are having a lot of difficulties and their relationship is hanging by a thread. “She really loves him and is desperate to for things to work out, but it’s hard to see how they are going to reconcile their differences.”
