Singer Amy Winehouse has reportedly been on a marathon 16-hour drinking session, and was pictured asleep outside a pub in the early hours.
Winehouse apparently started partying in Camden and moved on to various venues across London, meeting with actress Mischa Barton and Russell Brand's dad Ron.
The Sun reports that Barton clashed with Winehouse over her drinking, allegedly telling the singer that she had "had enough".
The taxi driver who took Amy to the Inn 1888 pub is reported to have said Amy complained that boyfriend Reg Traviss "has no respect for her".
The pub in Marylebone is owned by the parents of film director Traviss, who has been dating Winehouse for several weeks.
