Amy Winehouse blew off a date with London cops last week ... Amy, unreliable? Get outta here.
The fuzz wanted to ask Amy questions about an incident in which she allegedly socked Sherene Flash at the End of Summer Ball in London last month, after Flash asked to have her photo taken with the celebuwreck.
The cops tell us the appointment will be rescheduled, and no legal action will be taken at this time. Reports that she's going to be arrested for assault are not true ... though possibly just premature.
