First we had Kate Moss chaperoning Liv Tyler to the London premiere of Liv's new movie. Then last week we witnessed Stella McCartney and Gwynie arriving hand in hand at New York's Metropolitan Museum for the launch of the Jackie Kennedy retrospective. This is not to say that Stella and Gwynie or Kate and Liv are actually doing it, just that they wouldn't mind if we thought they were. The fact that Liv is practically engaged and Kate is rarely short of a date is neither here nor there.

Given the choice between Liz Hurley and Pamela Anderson bosom-wrestling at the Oscars, or Liz and Steve Bing, the man who has managed to do for the leather jacket what Jeremy Clarkson did for jeans, you begin to see there's no contest. The necessary qualifications are youth, decorativeness and a high cool rating - actual mutual affection is just an accidental bonus. If friendship was what it was all about, as opposed to image manipulation, then Stella would have been there with her sister and Kate with her one-time PA, Jess, but their YDC quotas just aren't in the ballpark. This is showbusiness. Youth is the No.1 requirement.
