Amy Winehouse's marriage is reportedly "hanging by a thread" after she watched her husband leave a party with another woman.
The 'Rehab' singer "went ballistic" when she saw Blake Fielder-Civil chatting intimately with supermodel Lily Cole, at the bash at London department store Harvey Nichols.
Blake then left with Lily, leaving Amy alone at the party 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 there open mouthed. Their marriage is hanging by a thread."
The tempestuous couple eventually sorted out their differences, but Amy is said to be fuming about the attention Lily gave Blake.
An insider told Britain's Daily 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."
The dinner party was held to launch Hollywood twins Mary-Kate and Ashley Olsen's new fashion label The Row.
The troubled pair have had a series of public bust-ups since marrying in Miami last May, the most severe saw both Amy and Blake embroiled in a blood-soaked argument in a busy London street in August. |
