Don’t look now, but Amy Winehouse is back lip-locking with ex-husband Blake Fielder-Civil.
The couple, who divorced last summer, cozily ate some tapas at Jamon Jamon, which has been a regular haunt for Winehouse, 26, in Camden, north London, Sunday.
Friends of the singer say there is nothing formal being discussed between the two, who have only seen each other a handful of times since he left jail last year. – Simon Perry
